[jira] [Commented] (YARN-10532) Capacity Scheduler Auto Queue Creation: Allow auto delete queue when queue is not being used

Generally looks good to me, but the latest patch has a whitespace error in TestAutoCreatedQueueDeletionPolicy.java, the CI will most likely complain about that. Otherwise if you upload a new patch, can you please also remove the unused Supplier imports (where applicable, TestAutoCreatedQueueDeletionPolicy and TestCapacitySchedulerNewQueueAutoCreation have it) and close the mockRM in TestSchedulingMonitor.testRMUpdateAutoCreatedQueueDeletionPolicy?

Qi Zhu commented on YARN-10532:
---
Thanks a lot [~gandras] for final check.
The yarn.scheduler.capacity in the property is actually in the property, this
is queue level setting for disabled auto deletion:
{code:java}
@Private
public boolean isAutoExpiredDeletionEnabled(String queuePath) {
boolean isAutoExpiredDeletionEnabled = getBoolean(
getQueuePrefix(queuePath) +
AUTO_CREATE_CHILD_QUEUE_AUTO_REMOVAL_ENABLE,
DEFAULT_AUTO_CREATE_CHILD_QUEUE_AUTO_REMOVAL_ENABLE);
return isAutoExpiredDeletionEnabled;
}
public static String getQueuePrefix(String queue) {
String queueName = PREFIX + queue + DOT;
return queueName;
}
@Private
public static final String PREFIX = "yarn.scheduler.capacity.";
{code}
Other things are fixed in latest patch.
[~pbacsko]
If you any other advice?
Thanks.

Andras Gyori commented on YARN-10532:

Hi [~zhuqi]. I have some final addition on the contribution (sorry for delaying
the commit). One major thing is:
* The auto queue removal switch is flawed. I am convinced that one would
expect to have yarn.scheduler.capacity in the property, but this is not the
case:
{code:java}
@Private
public static final String AUTO_CREATE_CHILD_QUEUE_AUTO_REMOVAL_ENABLE =
AUTO_QUEUE_CREATION_V2_PREFIX + "queue-auto-removal.enable";
{code}
There are some minor format issues in TestCapacitySchedulerNewQueueAutoCreation:
* There are still a lot of places where new Supplier is still used,
but sometimes it is replaced by a lambda. This is not consistent
* assertTrue(getNumApplications() == 0) asserts could be simplified to an
equals assert
Apart from those issues, the patch looks good to me.

Peter Bacsko commented on YARN-10532:
-
FIRST round review.
I might post more but these are that stand out to me right now.
1.
AbstractYarnScheduler:
{noformat}
public void removeQueue(CSQueue queueName) throws YarnException {
throw new YarnException(getClass().getSimpleName()
+ " does not support removing queues");
}
{noformat}
If this is an abstract class, just make this method abstract without
implementation:
{{public abstract void removeQueue(CSQueue queueName) throws YarnException;}}
2.
{noformat}
// When this queue has application submit to?
// This property only applies to dynamic queue,
// and will be used to check when the queue need to be removed.
{noformat}
Rephrase this comment a little bit:
{noformat}
// The timestamp of the last submitted application to this queue.
// Only applies to dynamic queues.
{noformat}
3.
{noformat}
// "Tab" the queue, so this queue won't be removed because of idle
timeout.
public void signalToSubmitToQueue() {
{noformat}
I'd comment that "Update the timestamp of the last submitted application".
Also, the method name is sounds weird to me. What it does is really simple.
Call it {{updateLastSubmittedTimeStamp()}}.
If you use the right naming, then the comment is probably unnecessary. We
don't need comments if the method is simple and easy to understand its purpose.
4. Instead of this:
{noformat}
// just for test
public void setLastSubmittedTimestamp(long lastSubmittedTimestamp) {
{noformat}
use this:
{noformat}
@VisibleForTesting
public void setLastSubmittedTimestamp(long lastSubmittedTimestamp) {
{noformat}
5. This comment is completely unnecessary I think:
{noformat}
// Expired queue, when there are no applications in queue,
// and the last submit time has been expired.
// Delete queue when expired deletion enabled.
{noformat}
It's obvious what the method is doing. Or if you insist on having a comment
there, just add "Timeout expired, delete the dynamic queue"
6. I suggest a better exception message:
{noformat}
throw new SchedulerDynamicEditException(
"The queue " + queue.getQueuePath()
+ " can't removed normally.");
{noformat}
It should say "The queue ABC cannot be removed because it's parent is null".
7. {{LOG.info("Removed queue: " + queue.getQueuePath());}} – not necessary to
log a successful removal. If there is no message, it means that the removal was
successful.
8. Typo in comment: {{// 300s for expired defualt}} --> "default"
9. These methods are used by the code itself, not just test:
{noformat}
@VisibleForTesting
public void prepareForAutoDeletion() {
...
@VisibleForTesting
public void triggerAutoDeletionForExpiredQueues() {
{noformat}
So "VisibleForTesting" should be removed.
10.
{noformat}
private void queueAutoDeletion(CSQueue checkQueue) {
//Scheduler update is asynchronous
if (checkQueue != null) {
{noformat}
Three things:
* {{queueAutoDeletion()}} - this method is a noun. Ideally, methods begin with
a verb. For example "deleteDynamicQueue()" or "deleteAutoCreatedQueue()".
* Also, why is it called "checkQueue"? Just call it "queue".
* The comment is confusing: "Scheduler update is asynchronous". Why is it
there? This statement does not tell me anything in this context. Does it refer
to the null-check?
11.
{noformat}
@Before
public void setUp() throws Exception {
// The expired time for deletion will be 1s
super.setUp();
}
{noformat}
This method is unnecessary, the setUp() method in the super class will be
called anyway.
12. Test methods: {{testEditSchedule}},
{{testCapacitySchedulerAutoQueueDeletion}},
{{testCapacitySchedulerAutoQueueDeletionDisabled}}
These test methods are long, but it's not my main problem. There are
{{Thread.sleep()}} calls inside. This is really problematic, especially short
sleeps like {{Thread.sleep(100)}}.
I have fixed many flaky tests where the test code were full of
{{Thread.sleep()}}. This must be avoided whever possible.
We should come up with a better solution, eg. polling a certain state
regularly, for example:
{noformat}
GenericTestUtils.waitFor(someObject.isConditionTrue(), 500, 10_000);
{noformat}
This method calls {{someObject.isConditionTrue()}} in every 500ms and it times
out after 10 seconds. In case of a timeout, a {{TimeoutException}} will be
thrown.

One last thing I have realised is that we did not have queue removal before, so we did not write tests for it. I think it is important to test this behaviour as well. In my opinion, adding a test case which covers some calculation checking (how does the normalised weight and absolute resources change after queue removal) in the same manner as we did it for queue addition test cases would be vital. > Capacity Scheduler Auto Queue Creation: Allow auto delete queue when queue is > not being used > > > Key: YARN-10532 > URL: https://issues.apache.org/jira/browse/YARN-10532 > Project: Hadoop YARN > Issue Type: Sub-task >Reporter: Wangda Tan >Assignee: Qi Zhu >Priority: Major > Attachments: YARN-10532.001.patch, YARN-10532.002.patch, > YARN-10532.003.patch, YARN-10532.004.patch, YARN-10532.005.patch, > YARN-10532.006.patch, YARN-10532.007.patch, YARN-10532.008.patch, > YARN-10532.009.patch, YARN-10532.010.patch, YARN-10532.011.patch, > YARN-10532.012.patch, YARN-10532.013.patch, YARN-10532.014.patch, > YARN-10532.015.patch, YARN-10532.016.patch, YARN-10532.017.patch, > YARN-10532.018.patch, YARN-10532.019.patch > > > It's better if we can delete auto-created queues when they are not in use for > a period of time (like 5 mins).

[ https://issues.apache.org/jira/browse/YARN-10532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17280065#comment-17280065 ] Qi Zhu commented on YARN-10532: --- Thanks a lot [~gandras] for patient review. In latest patch, I have fixed 1. MonitoringInterval related bug. 2. Queue-expiration-time related bug. 3. Add more reasonable test for TestCapacitySchedulerNewQueueAutoCreation. 4. We can disable all queues auto deletion by set it to -1. But i still think it is needed that we can disable a specific queue when other queues enable auto deletion. The logic now is reasonable.

Hi [~zhuqi] and thanks for addressing the feedbacks. I have tried this feature
on a cluster and did not work flawlessly. My observations are:
* The monitoringInterval is in milisecond, but the configuration value is in
second. This is a critical discrepancy and resulted in RM spamming. This should
be mitigated by:
{code:java}
monitoringInterval =
csConfig.getLong(CapacitySchedulerConfiguration.
AUTO_CREATE_CHILD_QUEUE_EXPIRED_TIME,
CapacitySchedulerConfiguration.
DEFAULT_AUTO_CREATE_CHILD_QUEUE_EXPIRED_TIME) * 1000;
{code}
* The queue-expiration-time is not prefixed, thus making the whole property
named auto-queue-creation-v2.queue-expiration-time instead of
yarn.scheduler.capacity.auto-queue-creation-v2.queue-expiration-time.
* There should be a separation of testing, and I would advise to change the
existing auto deletion tests in TestCapacitySchedulerNewQueueAutoCreation not
to invoke the policy itself, but rely only on CapacityScheduler like the
following example:
{code:java}
@Test
public void testCapacitySchedulerAutoQueueDeletion() throws Exception {
startScheduler();
csConf.setBoolean(
YarnConfiguration.RM_SCHEDULER_ENABLE_MONITORS, true);
csConf.set(YarnConfiguration.RM_SCHEDULER_MONITOR_POLICIES,
AutoCreatedQueueDeletionPolicy.class.getCanonicalName());
csConf.setAutoExpiredDeletionTime(2);
cs.reinitialize(csConf, mockRM.getRMContext());
Set policies = new HashSet<>();
policies.add(
AutoCreatedQueueDeletionPolicy.class.getCanonicalName());
Assert.assertTrue(
"No AutoCreatedQueueDeletionPolicy is present in running monitors",
cs.getSchedulingMonitorManager().isSameConfiguredPolicies(policies));
ApplicationAttemptId app = submitApp(cs, USER0,
"a2-auto", "root.a.a1-auto");
Thread.sleep(1000);
AbstractCSQueue a2 = (AbstractCSQueue) cs.getQueue(
"root.a.a1-auto.a2-auto");
Assert.assertNotNull("a2 is not present", a2);
Assert.assertTrue("a2 is not a dynamic queue",
a2.isDynamicQueue());
finishApp(app);
Thread.sleep(2000);
a2 = (AbstractCSQueue) cs.getQueue("root.a.a1-auto.a2-auto");
Assert.assertNull("a2 is not deleted", a2);
Thread.sleep(2000);
AbstractCSQueue a1 = (AbstractCSQueue) cs.getQueue("root.a.a1-auto");
Assert.assertNull("a1 is not deleted", a1);
csConf.setAutoExpiredDeletionTime(2);
cs.reinitialize(csConf, mockRM.getRMContext());
}
{code}
* The policy itself should only be invoked in its own test class, as you have
already done it.
* As I see it, the general way of disabling time sensitive values is to set it
to -1. This way, you would not need to handle two different property.

The overall logic seems good to me, but I still have some addition regarding the testing: * The new policy class should have its own tests, where you check the markedForDeletion and sentForDeletion sets with some mocked RM. Here you would not need to care about what RM does, when you send the event, just make sure the policy logic itself is correct. (check TestCapacitySchedulerLazyPreemption for example) * In TestCapacitySchedulerNewQueueAutoCreation checking the markedForDeletion set is a policy internal variable, which should be only checked in the policy test. In this test case, only the editSchedule should be invoked from the policy class, nothing else. * A test is missing for the case, when a queue has application, but policy is invoked. This is really important not to remove queues that have applications running, so it should be tested thoroughly. > Capacity Scheduler Auto Queue Creation: Allow auto delete queue when queue is > not being used > > > Key: YARN-10532 > URL: https://issues.apache.org/jira/browse/YARN-10532 > Project: Hadoop YARN > Issue Type: Sub-task >Reporter: Wangda Tan >Assignee: Qi Zhu >Priority: Major > Attachments: YARN-10532.001.patch, YARN-10532.002.patch, > YARN-10532.003.patch, YARN-10532.004.patch, YARN-10532.005.patch, > YARN-10532.006.patch, YARN-10532.007.patch, YARN-10532.008.patch, > YARN-10532.009.patch, YARN-10532.010.patch, YARN-10532.011.patch, > YARN-10532.012.patch, YARN-10532.013.patch, YARN-10532.014.patch > > > It's better if we can delete auto-created queues when they are not in use for > a period of time (like 5 mins).

Andras Gyori commented on YARN-10532:
-
Thank you [~zhuqi] for the new patch. My additions are:
* use the getLastSubmittedTimestamp instead of the explicit member variable
because of the locking mechanism
* AutoCreatedQueueDeletionEvent
** Please add license header
** The following line is redundant in AutoCreatedQueueDeletionPolicy:
{code:java}
assert null == scheduler : "Unexpected duplicate call to init";
{code}
instanceof CapacityScheduler covers this case
*
** monitoringInterval should only be a value of the
QUEUE_AUTO_REMOVAL_MONITORING_INTERVAL, I am not quite sure about the other
values there
** the getter methods should be marked visiblefortesting only
** there are unused setters/getters there
** reinitalize should be removed, I dont think we will use it anywhere
** getPolicyName should return the stringified name of the class, not a
hardcoded value
** please rethink method names, for example initQueues makes no sense in this
revision
* CapacityScheduler
** the removeQueue could be rewritten to:
{code:java}
writeLock.lock();
try {
LOG.info("Removing queue: " + queue.getQueuePath());
if (!(queue instanceof AbstractCSQueue)) {
throw new SchedulerDynamicEditException(
"The queue that we are asked " + "to remove (" +
queue.getQueuePath()
+ ") is not a DynamicQueue");
}
if (!((AbstractCSQueue) queue).isEligibleForAutoDeletion()) {
LOG.warn("Queue " + queue.getQueuePath() +
" is marked for deletion, but not eligible for deletion");
return;
}
ParentQueue parentQueue = (ParentQueue)queue.getParent();
if (parentQueue != null) {
((ParentQueue) queue.getParent()).removeChildQueue(queue);
} else {
throw new SchedulerDynamicEditException(
"The queue " + queue.getQueuePath()
+ " can't removed normally.");
}
if (parentQueue.childQueues.contains(queue) ||
queueManager.getQueue(queue.getQueuePath()) != null) {
throw new SchedulerDynamicEditException(
"The queue " + queue.getQueuePath()
+ " has not been removed normally.");
}
LOG.info("Removed queue: " + queue.getQueuePath());
} finally {
writeLock.unlock();
}
{code}
** If a queue is not eligible for auto deletion, we should not throw an error,
just a warning (this is a plausible scenario in case of a race condition)
* queue-auto-removal-monitoring-interval is redundant with
queue-expiration-time, but is a misleading name. Perhaps the
queue-expiration-time is the better one, this should be preferred.
* LeafQueue
** signalToSubmitToQueue should be renamed to signalSubmission
** I agree that the number of all applications should be taken into
consideration in isEligibleForAutoDeletion
* Please add more test cases and test the logic of the policy itself

Andras Gyori commented on YARN-10532:
-
Hi [~zhuqi], thank you for the patch! I have analysed the provided code and I
have the following suggestions:
h2. AbstractCSQueue
Since the queues have some common conditional, I think we could encapsulate
these logic in methods inside the queue, which greatly simplifies the overall
code. I would advise to add:
{code:java}
public boolean isEligibleForAutoDeletion() { return false; }
public boolean isInactiveDynamicQueue() {
long idleDurationSeconds = Time.monotonicNow() - lastSubmittedTimestamp;
return isDynamicQueue() && isEligibleForAutoDeletion() &&
(idleDurationSeconds > this.csContext.getConfiguration().
getAutoExpiredDeletionTime());
}
{code}
h2. LeafQueue
Since LeafQueues have their own way of deciding whether it is eligible for
deletion, override isEligibleForAutoDeletion:
{code:java}
@Override
public boolean isEligibleForAutoDeletion() {
return isDynamicQueue() && getNumActiveApplications() == 0;
}
{code}
h2. ParentQueue
Same goes for ParentQueues:
{code:java}
@Override
public boolean isEligibleForAutoDeletion() {
return isDynamicQueue() && getChildQueues().size() == 0;
}
{code}
Also, the lastSubmittedTimestamp means something else in case of ParentQueues.
When we add a new child queue, we refresh this timestamp, just as we refreshed
the LeafQueue's timestamp on application submission:
{code:java}
private CSQueue addDynamicChildQueue(String childQueuePath, boolean isLeaf)
throws SchedulerDynamicEditException {
...
CSQueue newQueue = createNewQueue(childQueuePath, isLeaf);
this.childQueues.add(newQueue);
signalToSubmitToQueue();
...
}
{code}
h2. CapacityScheduler
The logic in CapacityScheduler#AutoCreatedQueueDeletion (which violates the
Java naming convention by the way, so it should be renamed) will be simplified
to:
{code:java}
private void AutoCreatedQueueDeletion(CSQueue checkQueue)
throws SchedulerDynamicEditException{
writeLock.lock();
try {
if (checkQueue instanceof AbstractCSQueue
&& ((AbstractCSQueue) checkQueue).isInactiveDynamicQueue()) {
removeQueue(checkQueue);
}
} finally {
writeLock.lock();
}
}
{code}
h2. AutoDeletionForExpiredQueuePolicy
I think this policy should be changed a bit. I advise to add two sets:
{code:java}
private Set markedForDeletion = new HashSet<>();
private Set sentForDeletion = new HashSet<>();
{code}
* markedForDeletion: in each interval, this set is extended by queues that are
eligible for auto deletion
* sentForDeletion: if in the next interval, there is queue, that is eligible
for auto deletion, and is already marked for deletion, move it to this queue
* if a queue is in markedForDeletion in the next interval, but not moved to
sentForDeletion, its mark should be reset (therefore clear the
markedForDeletion)
The logic to invoke in each interval is:
{code:java}
for (Map.Entry queues : scheduler
.getCapacitySchedulerQueueManager()
.getQueues().entrySet()) {
String queueName = queues.getKey();
CSQueue queue = queues.getValue();
Set newMarks = new HashSet<>();
if (queue instanceof AbstractCSQueue &&
((AbstractCSQueue) queue).isEligibleForAutoDeletion()) {
if (markedForDeletion.contains(queueName)) {
sentForDeletion.add(queueName);
markedForDeletion.remove(queueName);
} else {
newMarks.add(queueName);
}
}
markedForDeletion.clear();
markedForDeletion.addAll(newMarks);
}
for (String queueName : sentForDeletion) {
CSQueue checkQueue =
scheduler.getCapacitySchedulerQueueManager().
getQueue(queueName);
queueAutoDeletionCheck(checkQueue);
}
sentForDeletion.clear();
{code}
The monitoringInterval should be set to the value of the queue-expiration-time,
which you have introduced.
{code:java}
monitoringInterval = csConfig.getAutoExpiredDeletionTime(); {code}
Also please fix the following items:
* AutoCreatedQueueDeletionCheckEvent should be renamed to only
AutoCreatedQueueDeletionEvent
* AutoCreatedQueueDeletion should be renamed to removeAutoCreatedQueue
* AutoDeletionForExpiredQueuePolicy should be renamed to
AutoCreatedQueueDeletionPolicy
* The config expired-deletion-enabled should be renamed to
queue-auto-removal.enabled
* The config expired-deletion-time should be renamed to queue-expiration-time
* There are a handful of unused imports and methods, which should be removed
* Please do not use wildcard import in CapacityScheduler (line 42)

I have created a new Policy "(maybe we can make it runnable by default so we don't have to create another config) as [~wangda] suggested". The policy just simply monitor queue last used time and delete queues when needed. We can enable this, by adding AutoDeletionForExpiredQueuePolicy to the conf : "scheduler.monitor.policies". I also handled deletion of ParentQueues which without child queues. And i removed the reinitialize related logic, i think we don't need it when default enabled auto deletion. If you any other thoughts.

[ https://issues.apache.org/jira/browse/YARN-10532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17272968#comment-17272968 ] Andras Gyori commented on YARN-10532: - Thank you [~zhuqi] for the patch. I have come up with several points regarding this approach * In my opinion, implementing auto queue deletion for the legacy auto queue logic is not justified. Old CS users have their own way of keeping their queue hierarchy clean, thus providing this feature would be of little use for them. As for new CS users, they are encouraged to use the new auto queue creation. We should encourage the userbase to move away from ManagedParents, as the code is hard to maintain and very hard to reason about. * I think the approach chosen for this patch is hard to maintain because: ** Does not have a central point where the dynamic queue deletion happens (this was a major pain point of weight calculation as well, we should not repeat this mistake again). QueueManagementChanges and updateQueues both have twisted logic, which reduces readability. ** It does not cover all cases. If I understand correctly, the auto deletion only triggered if CS is reinitialised or a queue management change occurs. In my opinion, we should not rely on events of the users, which may, or may not happen. ** It does not handle deletion of ParentQueues. I think childless ParentQueues should get removed as well. My idea of implementing automatic queue deletion somewhat similar to a garbage collector: # Run a background thread, that periodically checks the whole queue hierarchy (maybe we could store the references of all the dynamic queues, in order to eliminate the cost of traversing the hierarchy) # Store the timestamp when a dynamic reaches 0 application (either in the queue itself or in an external map) # Mark the queues for deletion, that has been without application for a configured time ## Marking introduces a grace period, to avoid race conditions (namely, delete a queue in the same as an application has been submitted ## Application submission to marked queues should be rejected or make the mapping rules step to the next rule # After the grace period, check that the marked queues does not have any application running, and: ## Delete, if active application number is still == 0 ## Remove mark and timestamp if active application number > 0 # Remove dynamic ParentQueues the same way, but instead of checking active applications, check the number of children Now, I see that marking would introduce a surprising behaviour, but I can not come up with a way that is less disruptive and solves the race condition at the same time. > Capacity Scheduler Auto Queue Creation: Allow auto delete queue when queue is > not being used > > > Key: YARN-10532 > URL: https://issues.apache.org/jira/browse/YARN-10532 > Project: Hadoop YARN > Issue Type: Sub-task >Reporter: Wangda Tan >Assignee: zhuqi >Priority: Major > Attachments: YARN-10532.001.patch, YARN-10532.002.patch, > YARN-10532.003.patch, YARN-10532.004.patch, YARN-10532.005.patch, > YARN-10532.006.patch, YARN-10532.007.patch > > > It's better if we can delete auto-created queues when they are not in use for > a period of time (like 5 mins).

The latest patch, double check the
"An additional requirement we should keep in mind:
Scenario A:
{code:java}
- At time T0, policy signals scheduler to delete queue A (an auto created
queue).
- Before the signal arrives to scheduler, an app submitted to scheduler (T1).
T1 > T0
- When at T2 (T2 > T1), the signal arrived at scheduler, scheduler should avoid
removing the queue A because now it is used.{code}
Scenario B:
{code:java}
- At time T0, policy signals scheduler to delete queue A (an auto created
queue).
- At T1 (T1 > T0), scheduler got the signal and deleted the queue.
- At T2 (T2 > T1), an app submitted to scheduler.
Scheduler should immediately recreate the queue, in another word, deleting an
dynamic queue should NEVER fail a submitted application.{code}
"
This will not happen:
Scenario A confirmed by :
Double check before deletion, pass the latest last submitted time, and get
before remove again and compare them. All will in the queue write lock.
{code:java}
// Double check for the lastSubmitTime has been expired.
// In case if now, there is a new submitted app.
if (queue instanceof LeafQueue &&
((LeafQueue) queue).isDynamicQueue()) {
LeafQueue underDeleted = (LeafQueue)queue;
if (underDeleted.getLastSubmittedTimestamp() != lastSubmittedTime) {
throw new SchedulerDynamicEditException("This should not happen, " +
"trying to remove queue= " + childQueuePath
+ ", however the queue has new submitted apps.");
}
} else {
throw new SchedulerDynamicEditException(
"This should not happen, can't remove queue= " + childQueuePath
+ " is not a leafQueue or not a dynamic queue.");
}
// Now we can do remove and update
this.childQueues.remove(queue);
this.scheduler.getCapacitySchedulerQueueManager()
.removeQueue(queue.getQueuePath());
{code}
Signal will also update this in the write lock:
{code:java}
@Override
public void submitApplication(ApplicationId applicationId, String userName,
String queue) throws AccessControlException {
// Careful! Locking order is important!
validateSubmitApplication(applicationId, userName, queue);
// Signal to queue submit time in dynamic queue
if (this.isDynamicQueue()) {
signalToSubmitToQueue();
}
// Inform the parent queue
try {
getParent().submitApplication(applicationId, userName, queue);
} catch (AccessControlException ace) {
LOG.info("Failed to submit application to parent-queue: " +
getParent().getQueuePath(), ace);
throw ace;
}
}
// "Tab" the queue, so this queue won't be removed because of idle timeout.
public void signalToSubmitToQueue() {
writeLock.lock();
try {
this.lastSubmittedTimestamp = System.currentTimeMillis();
} finally {
writeLock.unlock();
}
}
{code}
Scenario B confirmed by :
in addApplication
and addApplicationOnRecovery.
{code:java}
// If the queue has been deleted for expired.
// - At time T0, policy signals scheduler to delete queue A (an auto created
queue).
// - At T1 (T1 > T0), scheduler got the signal and deleted the queue.
// - At T2 (T2 > T1), an app submitted to scheduler.
//
// Scheduler should immediately recreate the queue, in another word,
// deleting an dynamic queue should NEVER fail a submitted application.
// This case queue may be null later
// So add queue write lock here
try {
((AbstractCSQueue) queue).writeLock.lock();

long lastActive =
getLeafQueueState(leafQueue, nodeLabel).getMostRecentActivationTime();
long lastDeactive =
getLeafQueueState(leafQueue, nodeLabel).getMostRecentDeactivationTime();
// Check if need delete when expired.
if (lastActive >= lastDeactive
|| (lastDeactive - lastActive)/1000 <=
scheduler.getConfiguration().
getAutoExpiredDeletionTime(managedParentQueue.getQueuePath())
|| leafQueue.getAllApplications().size() > 0) {
isExpired = false;
}
{code}
For new auto created leaf queue:
{code:java}
private synchronized void computeDynamicLeafQueueChanges(LeafQueue leafQueue)
throws SchedulerDynamicEditException {
// Expired queue, when there are no running in leafQueue
// and the last submit time has been expired
// Delete queue when expired deletion enabled.
ParentQueue parentQueue = (ParentQueue) leafQueue.getParent();
if (parentQueue == null) {
throw new SchedulerDynamicEditException("Parent " +
"queue should not be null for auto deletion!");
}
long idleDuration =
(System.currentTimeMillis()
- leafQueue.getLastSubmittedTimestamp())/1000;
if (leafQueue.getAllApplications().size() ==0
&& idleDuration > this.getConfiguration()
.getAutoExpiredDeletionTime(leafQueue.getParent().getQueuePath())
&& this.getConfiguration().
isAutoExpiredDeletionEnabled(leafQueue.getParent().getQueuePath())){
LeafQueue removed = parentQueue.
removeDynamicLeafQueue(leafQueue.getQueuePath());
if (removed != null) {
this.getCapacitySchedulerQueueManager().
removeQueue(leafQueue.getQueuePath());
}
}
}
{code}
2. Support policy not enabled with Reinitialize update deletion:
{code:java}
private void updateQueues(CSQueueStore existingQueues,
CSQueueStore newQueues) {
CapacitySchedulerConfiguration conf = csContext.getConfiguration();
for (CSQueue queue : newQueues.getQueues()) {
if (existingQueues.get(queue.getQueuePath()) == null) {
existingQueues.add(queue);
}
}
for (CSQueue queue : existingQueues.getQueues()) {
// should also support for auto created for expired deletion
// 1. handle old auto created deletion for reinitializeQueues
// 2. handle new auto created deletion for reinitializeQueues
if ((queue.getParent() != null && queue instanceof AutoCreatedLeafQueue &&
conf.isAutoExpiredDeletionEnabled(queue.getParent().getQueuePath())
&& (newQueues.get(queue.getQueuePath())) == null &&
((AutoCreatedLeafQueue) queue).isExpiredQueue())
||
(queue.getParent() != null && queue instanceof LeafQueue &&
((LeafQueue) queue).isDynamicQueue() &&
conf.isAutoExpiredDeletionEnabled(queue.getParent().getQueuePath())
&& (newQueues.get(queue.getQueuePath())) == null &&
((System.currentTimeMillis() -
((LeafQueue)queue).getLastSubmittedTimestamp())
>
conf.getAutoExpiredDeletionTime(queue.getParent().getQueuePath())) &&
((LeafQueue)queue).getAllApplications().size() == 0)
||
!((AbstractCSQueue) queue).isDynamicQueue() && newQueues.get(
queue.getQueuePath()) == null && !(
queue instanceof AutoCreatedLeafQueue && conf
.isAutoCreateChildQueueEnabled(
queue.getParent().getQueuePath( {
existingQueues.remove(queue);
}
}
{code}
Other remaining to do:
# If we need to support auto deletion also for parent queues.
# I will deep into more details about all the corner cases.

Wangda Tan commented on YARN-10532:

[~zhuqi], thanks for the patch, I took a brief look (nothing in detail yet). I
think here're my overall thoughts:
1) Instead of changing GuaranteedOrZeroCapacityOverTimePolicy, I suggest
creating a new Policy (maybe we can make it runnable by default so we don't
have to create another config). The policy just simply monitor queue last used
time and delete queues when needed.
2) The latest patch only remove queue when reinitialize queue is called, it is
not a frequent used method, we have cluster which doesn't have queue
reinitialize called for a long period of time. Can we just call it from the
policy (then we may need to introduce a method in CapacityScheduler to delete
queue).
3) When we delete a queue, we need to check inside Scheduler to make sure 1)
there's nothing running in the queue; 2) last usage timestamp is expired. We
need to do this to avoid racing condition that Policy think a queue is
deletable but Scheduler doesn't.
4) Policy modifies "expiredQueue" field, I suggest to make Policy just read the
state, and let Scheduler delete it.
5) An additional requirement we should keep in mind:
Scenario A:
{code:java}
- At time T0, policy signals scheduler to delete queue A (an auto created
queue).
- Before the signal arrives to scheduler, an app submitted to scheduler (T1).
T1 > T0
- When at T2 (T2 > T1), the signal arrived at scheduler, scheduler should avoid
removing the queue A because now it is used.{code}
Scenario B:
{code:java}
- At time T0, policy signals scheduler to delete queue A (an auto created
queue).
- At T1 (T1 > T0), scheduler got the signal and deleted the queue.
- At T2 (T2 > T1), an app submitted to scheduler.
Scheduler should immediately recreate the queue, in another word, deleting an
dynamic queue should NEVER fail a submitted application.{code}

[~gandras]
In original auto created leaf queue, there are policy
GuaranteedOrZeroCapacityOverTimePolicy can:
* Store the timestamp of every empty queues
* Asynchronously check in QueueManagementDynamicEditPolicy
{code:java}
@Override
public void editSchedule() {
long startTs = clock.getTime();
initQueues();
manageAutoCreatedLeafQueues();
if (LOG.isDebugEnabled()) {
LOG.debug("Total time used=" + (clock.getTime() - startTs) + " ms.");
}
}
{code}
Something just like preemption policy.
Can commit changes to expired inactive auto queues, and make other changes.
* This can reuse for deletion when expiration, it's realized by this patch.
But in new auto created queue, there are no policy, this leads me to ask the
question in YARN-10564
If we need to realize this similar policy, or just add some thread to do this.

I think this should be approached in a way, that allows: * Periodically check all the queues in the hierarchy (this should be done in a different thread asynchronously, do not know if we can reuse an existing one, or we need to introduce a garbage collector thread) * Store the timestamp of every empty queues * If a queue remains empty after X seconds, we delete it (probably a configurable value) * We should keep in mind the queue hierarchy as well, because there could be empty dynamic parent queues this way, which also need to be purged. > Capacity Scheduler Auto Queue Creation: Allow auto delete queue when queue is > not being used > > > Key: YARN-10532 > URL: https://issues.apache.org/jira/browse/YARN-10532 > Project: Hadoop YARN > Issue Type: Sub-task >Reporter: Wangda Tan >Assignee: zhuqi >Priority: Major > Attachments: YARN-10532.001.patch > > > It's better if we can delete auto-created queues when they are not in use for > a period of time (like 5 mins).
