It looks like folks are generally OK with getting this patch in and deal with
further clean up for mixed config mode in a follow up Jira. +_I plan to get it
in by today my time.

Ok, we should handle this later, because there are a lot of other important

Thanks [~zhuqi], [~bteke] and review from [~sunilg].
I suggest let's go ahead with ver.010, and deal with the abs resource in a
follow-up Jira. This Jira is already very large and we need more clean up for
the absolute resource + weight + percent rather than just fixing the problem
itself. Also, this Jira blocked a number of efforts such as YARN-10506.
Thoughts?

Uploaded patch 11 containing the said modification, however it causes an issue
in
TestAbsoluteResourceConfiguration.testSimpleMinMaxResourceConfigurartionPerQueue.
I'll look into it, in the meantime patch 11 can be considered obsolete.

Thanks for your confirm. We just should take care of AutoCreatedLeafQueue with
absolute resource, but we should let AutoCreatedLeafQueue with capacity go, no
other objections.
Thanks [~sunilg] for the review.

I came to the same conclusion in my comment
[above|https://issues.apache.org/jira/browse/YARN-10504?focusedCommentId=17261549=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17261549],
so I agree with your suggestion. Will upload a patch containing it, if no
objections.
Thanks [~sunilg] for the review! I'll create the followup jira.

Sunil G commented on YARN-10504:
I checked the latest patch over the weekend. There are no major comments from
my side on this.
However, I think some more detailed refactoring is needed which should address
a common way to handle the weight, percentage, absolute values etc. This could
help to avoid a few hardcodings as well. So let's create another Jira to track
this.
If test cases are fine, then I am generally +ve in getting this in soon. Thanks.
Thanks, [~bteke] [~wangda] [~zhuqi] for the efforts on this.

When used the absolute resource in the autoCreatedLeafQueue, the logic is :
1.Initialize the update absolute template:
{code:java}
protected AutoCreatedLeafQueueConfig.Builder initializeLeafQueueConfigs()
throws IOException {
//Update the absolute template
if (this.capacityConfigType.equals(CapacityConfigType.ABSOLUTE_RESOURCE)) {
updateQueueCapacities(queueCapacities);
}
...
builder.capacities(queueCapacities);
return builder;
}
//get resource value in
private Resource internalGetLabeledResourceRequirementForQueue(String queue,
String label, Set resourceTypes, String suffix) {
...
if (matcher.find()) {
// Get the sub-group.
String subGroup = matcher.group(0);
if (subGroup.trim().isEmpty()) {
return Resources.none();
}
subGroup = subGroup.substring(1, subGroup.length() - 1);
for (String kvPair : subGroup.trim().split(",")) {
String[] splits = kvPair.split("=");
// Ensure that each sub string is key value pair separated by '='.
if (splits != null && splits.length > 1) {
updateResourceValuesFromConfig(resourceTypes, resource, splits);
}
}
}
...
return resource;
}
// Update in ManagedParentQueue's updateQueueCapacities
private void updateQueueCapacities(QueueCapacities queueCapacities) {
for (String label : queueCapacities.getExistingNodeLabels()) {
queueCapacities.setCapacity(label,
this.csContext.getResourceCalculator().divide(
this.csContext.getClusterResource(),
this.csContext.getConfiguration().getMinimumResourceRequirement(
label,
this.csContext.getConfiguration()
.getAutoCreatedQueueTemplateConfPrefix(getQueuePath()),
resourceTypes),
getQueueResourceQuotas().getConfiguredMinResource(label)));
Resource childMaxResource = this.csContext.getConfiguration()
.getMaximumResourceRequirement(label,
this.csContext.getConfiguration()
.getAutoCreatedQueueTemplateConfPrefix(getQueuePath()),
resourceTypes);
Resource parentMaxRes = getQueueResourceQuotas()
.getConfiguredMaxResource(label);
Resource effMaxResource = Resources.min(
this.csContext.getResourceCalculator(),
this.csContext.getClusterResource(),
childMaxResource.equals(Resources.none()) ? parentMaxRes
: childMaxResource,
parentMaxRes);
queueCapacities.setMaximumCapacity(
label, this.csContext.getResourceCalculator().divide(
this.csContext.getClusterResource(),
effMaxResource,
getQueueResourceQuotas().getConfiguredMaxResource(label)));
queueCapacities.setAbsoluteCapacity(
label, queueCapacities.getCapacity(label)
* getQueueCapacities().getAbsoluteCapacity(label));
queueCapacities.setAbsoluteMaximumCapacity(label,
queueCapacities.getMaximumCapacity(label)
* getQueueCapacities().getAbsoluteMaximumCapacity(label));
}
} {code}
2. Now, the capacity has been updated to absolute resource based value in
addChildQueue:
It back to the absolute resource in : setEffectiveMinResource
{code:java}
public void mergeCapacities(QueueCapacities capacities) {
for ( String nodeLabel : capacities.getExistingNodeLabels()) {
queueCapacities.setCapacity(nodeLabel,
capacities.getCapacity(nodeLabel));
queueCapacities.setAbsoluteCapacity(nodeLabel, capacities
.getAbsoluteCapacity(nodeLabel));
queueCapacities.setMaximumCapacity(nodeLabel, capacities
.getMaximumCapacity(nodeLabel));
queueCapacities.setAbsoluteMaximumCapacity(nodeLabel, capacities
.getAbsoluteMaximumCapacity(nodeLabel));
Resource resourceByLabel = labelManager.getResourceByLabel(nodeLabel,
csContext.getClusterResource());
getQueueResourceQuotas().setEffectiveMinResource(nodeLabel,
Resources.multiply(resourceByLabel,
queueCapacities.getAbsoluteCapacity(nodeLabel)));
getQueueResourceQuotas().setEffectiveMaxResource(nodeLabel,
Resources.multiply(resourceByLabel, queueCapacities
.getAbsoluteMaximumCapacity(nodeLabel)));
}
}{code}
The effective resource have been updated to autoCreatedLeafQueue already.
3. Then, in LeafQueue's updateClusterResource:
{code:java}
public void updateClusterResource(Resource clusterResource,
ResourceLimits currentResourceLimits) {
writeLock.lock();
try {
...
super.updateEffectiveResources(clusterResource);
...}
}{code}
We can change the updateEffectiveResources , to get consistent result to orgin:
{code:java}
void updateEffectiveResources(Resource clusterResource) {
Set

Uploaded ver.009, fixed more test failures. I run it locally and I think most
test cases should pass. Let's see how Jenkins's result looks like.

Still see some issues around auto created leaf queue, fixed a number of issues
introduced by the latest changes in ParentQueue.setChildQueues.
Unit tests:
- TestRMWebServicesForCSWithPartitions:
[FIXED] There's bad assumption for #resourceByPartition returned. When the
queue is initialized, there's no usage thus there should have no
resourceByPartition. Updated tests to not test #resourceByPartition.
- TestRMWebServices:
[FIXED] testValidateAndGetSchedulerConfigurationInvalidConfig: This is a bad
test which checks returned plain text of exception, we should avoid do that.
fix: Changed to just check it is an IOException instead of checking the actual
text.
* TestAbsoluteResourceConfiguration
[PENDING] testSimpleMinMaxResourceConfigurartionPerQueue:
this is still pending, because now AutoCreatedLeafQueue depends on
mergeCapacities, which calculate capacity first, then use the capacity to
calculate absolute min resource.
It can cause a change in effectiveMinResource value even if cluster has
sufficient resource.
We should look into this once we finish the YARN-10506. Now temporarily update
test to use the wrong value to unblock tests.
fixed rest issues.
Will continue investigate.

[~wangda], [~zhuqi]
Added a small new patch. ver.6 had a small issue in
ParentQueue.getCapacityConfigurationTypeForQueues, where if the passed queues
collection was empty the iterator where the mixed mode check was implemented
threw a NoSuchElementException, causing all of the AutoCreatedTests to fail.
Also setChildQueues has a similar mixed mode check, where the root queue is
included in the check, causing an unnecessary exception. So I extended that if
as well. Additionally I added [~zhuqi]'s suggestion to
LeafQueue.updateClusterResource.
There is one more issue: now 2 of the TestAbsoluteResourceWithAutoQueue tests
are failing, because the apps are stuck in SUBMITTED state. [~wangda] do you
have an idea on this one?

Updated ver.6 patch, which includes the following:
1) Unit tests to test end to end capability and mixed percentage/weight mode.
2) Rewrite ParentQueue.setChildQueues. It was a bit messy before. Now it
enforced more strict checks, and rewrote check statements for better
readability.
[~zhuqi]/[~bteke] /[~gandras] , I haven't addressed your comment, so it will be
nice if you can help to make the changes. (And again, please add a comment if
you plan to do that to avoid editing the same code).

Make sense [~zhuqi].
[~bteke]/[~gandras] , if you're not making changes to the patch, [~zhuqi] can
you take care of the issue?
I plan to add a few more test case coverages for the weight mode
today/tomorrow. I will not touch any existing logic.

1. The {{updateAbsoluteCapacitiesAndRelatedFields should update
maxApplications, but in some case, for example:}}
{{ in TestCapacitySchedulerAutoQueueCreation ->
}}testAutoCreatedQueueActivationDeactivation
{code:java}
//submit user_3 app. This cant be allocated since there is no capacity
// in NO_LABEL, SSD but can be in GPU label
submitApp(mockRM, parentQueue, USER3, USER3, 4, 1);
final CSQueue user3LeafQueue = cs.getQueue(USER3);
validateCapacities((AutoCreatedLeafQueue) user3LeafQueue, 0.0f, 0.0f,
1.0f, 1.0f);
validateCapacitiesByLabel((ManagedParentQueue) parentQueue,
(AutoCreatedLeafQueue)
user3LeafQueue, NODEL_LABEL_GPU);
{code}
The case is no capacity in user_3 autoCreatedLeafQueue, so in
{{updateAbsoluteCapacitiesAndRelatedFields}}
{code:java}
private void updateAbsoluteCapacitiesAndRelatedFields() {
updateAbsoluteCapacities();
CapacitySchedulerConfiguration schedulerConf = csContext.getConfiguration();
// If maxApplications not set, use the system total max app, apply newly
// calculated abs capacity of the queue.
if (maxApplications <= 0) {
int maxSystemApps = schedulerConf.
getMaximumSystemApplications();
maxApplications =
(int) (maxSystemApps * queueCapacities.getAbsoluteCapacity());
}
maxApplicationsPerUser = Math.min(maxApplications,
(int) (maxApplications * (usersManager.getUserLimit() / 100.0f)
* usersManager.getUserLimitFactor()));
}
// because capacities will update to 0
if (availableCapacity >= leafQueueTemplateCapacities
.getAbsoluteCapacity(nodeLabel)) {
updateCapacityFromTemplate(capacities, nodeLabel);
activate(leafQueue, nodeLabel);
} else{
updateToZeroCapacity(capacities, nodeLabel);
}
// And because, the update will be after reinitializeFromTemplate
final AutoCreatedLeafQueueConfig initialLeafQueueTemplate =
queueManagementPolicy.getInitialLeafQueueConfiguration(leafQueue);
leafQueue.reinitializeFromTemplate(initialLeafQueueTemplate);
// Do one update cluster resource call to make sure all absolute resources
// effective resources are updated.
updateClusterResource(this.csContext.getClusterResource(),
new ResourceLimits(this.csContext.getClusterResource()));{code}
The maxApplications and maxApplicationsPerUser will be 0.
So will should handle in new logic in
//TODO recalculate max applications because they can depend on capacity
The todo should be removed, just pass the AutoCreatedLeafQueue case now, or add
logic to make this case's maxApplications to a fixed default num.
2. As mentioned by [~bteke]
"Sharing my latest findings on TestAbsoluteResourceWithAutoQueue failure:
{{AutoCreatedLeafQueue#reinitializeFromTemplate }}was refactored, now the
getting and merging the QueueCapacities happens *before* calling the
{{ParentQueue#updateClusterResource}} (and
{{LeafQueue#updateClusterResource}}). In \{{LeafQueue#updateClusterResource
}}the \{{AbstractCSQueue#updateEffectiveResources }}is called where the
effectiveMinResource of the created queue is overridden with the template's
effectiveMinResources which is exactly the same the test is getting in the
asserts."
We should changed the {{LeafQueue updateClusterResource }}to:
{code:java}
// public void updateClusterResource(Resource clusterResource,
ResourceLimits currentResourceLimits) {
writeLock.lock();
try {
...
if (!(this instanceof AutoCreatedLeafQueue)) {
super.updateEffectiveResources(clusterResource);
}
}{code}
It will fix absolute case TestAbsoluteResourceWithAutoQueue .
If you any other advice?
Thanks.

1) AbstractCSQueue, lots of format changes, can we revert all format change
(change spaces). Since it will cause issues when backport and reviews
2) LeafQueue:
There're two TODOs:
//TODO recalculate max applications because they can depend on capacity
//TODO recalculate max applications because they can depend on capacity
I think it took care by the {{updateAbsoluteCapacitiesAndRelatedFields}},
please double check, and if it is correct, we should remove the TODOs
3) TestAbsoluteResourceWithAutoQueue:
I added a TODO:
TODO: Wangda: I think this test case is not correct, Sunil could help look
// into details.
4) TestCapacitySchedulerAutoCreatedQueueBase.java
I also added a TODO
// TODO: Wangda, I think this is a wrong test, it doesn't consider rounding
...
[~bteke], [~gandras], [~zhuqi] if any of you plan to make change to the patch,
please add a comment to the JIRA so others will know, otherwise the patch will
be hard to merge.

Sharing my latest findings on TestAbsoluteResourceWithAutoQueue failure:
{{AutoCreatedLeafQueue#reinitializeFromTemplate }}was refactored, now the
getting and merging the QueueCapacities happens *before* calling the
{{ParentQueue#updateClusterResource}} (and
{{LeafQueue#updateClusterResource}}). In {{LeafQueue#updateClusterResource
}}the {{AbstractCSQueue#updateEffectiveResources }}is called where the
effectiveMinResource of the created queue is overridden with the template's
effectiveMinResources which is exactly the same the test is getting in the
asserts.
{code:java}
void updateEffectiveResources(Resource clusterResource) {
Set configuredNodelabels =
csContext.getConfiguration().getConfiguredNodeLabels(getQueuePath());
for (String label : configuredNodelabels) {
Resource resourceByLabel = labelManager.getResourceByLabel(label,
clusterResource); Resource minResource =
queueResourceQuotas.getConfiguredMinResource(
label); // Update effective resource (min/max) to each child
queue.
if (getCapacityConfigType().equals(
CapacityConfigType.ABSOLUTE_RESOURCE)) {
queueResourceQuotas.setEffectiveMinResource(label,
getMinResourceNormalized(queuePath,
((ParentQueue) parent).getEffectiveMinRatioPerResource(),
minResource));
...{code}

Hey [~zhuqi],
Thanks for your updates. Took the liberty to refactor/include your changes in
my latest patch. Also based on our offline discussion with [~gandras] I removed
some parts of his 002 patch, as it will be handled differently. As you have
mentioned the AutoQueueCreation should now work, because the leafQueueTemplates
should now have the correct absolute capacities. I will now turn to the
AbsoluteResourceWithAutoQueue issue and handle the maxApplications in auto
created cases.
If you upload a new patch please use the 005 patch as base, because that
contains the latest from our side and also includes your changes from 003/004
patch.
Thanks!

I attached a patch to fix the absolute update related error in
AutoCreatedLeafQueue. But still some corner cases should be fixed, and i add
(fix me) to them , such as the max application limit in AutoCreatedLeafQueue
update, i wish it will be helpful.
Thanks.

Thanks [~wangda] for the details, I understand the decisions made in the patch
creation. Since queue parsing phase is no longer guaranteed to be complete, I
think the absCapacity > absMaxCapacity check should be deferred to a later
point, where we are sure, that every value had already been calculated. This is
necessary, because the tests are failing due to this check giving the wrong
assumption (absCapacities are partially calculated at that point).

Regarding the AutoCreatedLeafQueue: we are looking into the issue. Cuurently it
seems like the way the mock setup is structured the updateClusterResource is
not called at the correct time. We'll update the patch once the issue is fixed.

[~gandras],
Thanks for updating this, your observation is correct: In the original patch I
moved calculation of absolute percentage from config parsing phase to refresh
queue phase. Why I did that?
- Because of the weight mode will impact relative percentage, queue parsing
phase is no longer able to get all percentages of queues in one shot. Even
though we can normalize weight values during parsing phase, however, if we have
dynamic queues under the same parent, parsing phase cannot get all percentage
correctly calcuated.
- The previous calculation of config properties are bit ad-hoc: Some values are
calculated during setupQueueConfigs, some values calculated in
reinitialization, some values calculated in updateClusterResource. The patch I
moved many of the config properties which needs runtime calculation (such as
absolute percentage) to updateCluserResources. (And removed from
setupQueueConfig)
- I noticed failure of AutoCreatedLeafQueue, but I didn't get a chance to dig
more for the root cause, sjince updateClusterResource will be called for
AutoCreatedLeafQueue, I don't know why it is still failing. Is it a test issue
or production issue? (Please note that updateClusterResource of CSQueue will be
called during CS init, reinit, and resource changes).

Andras Gyori commented on YARN-10504:
-
Fixed the following test classes:
* TestCSMaxRunningAppsEnforcer
* TestNodeLabelContainerAllocation
* TestQueueParsing
* TestCapacitySchedulerDynamicBehavior
* TestCapacitySchedulerPlanFollower
I have identified a problematic part of the change, which must be addressed,
because it affects a lot of classes.
The *CSQueueUtils* has been changed and now only the
*loadCapacitiesByLabelsFromConf* method is used. Several tests are failing
because:
{code:java}
float absCapacity = queueCapacities.getCapacity(label);
float absMaxCapacity = queueCapacities.getMaximumCapacity(label);
if (absCapacity > absMaxCapacity) {
throw new IllegalArgumentException("Illegal queue capacity setting "
+ "(abs-capacity=" + absCapacity + ") > (abs-maximum-capacity="
+ absMaxCapacity + ") for queue=["
+ queuePath + "],label=[" + label + "]");
}{code}
Now, it might be a typo or a bug, because absCapacity here is NOT the actual
absolute capacity, but the regular capacity. This leads to an other problem,
namely the absolute capacity is not calculated for LeafQueue and PlanQueue,
which leaves the absolute capacity as 0. This was previously calculated in
*CSQueueUtils*. The *AbstractCSQueue*#*updateAbsoluteCapacity* contains the
same logic, but the AutoCreatedLeafQueue tests are still failing, and probably
due to this issue.
The questions are:
* Is the check in loadCapacitiesByLabelsFromConf correct, or absCapacity
should be equals to queueCapacities.getAbsolutCapacity()
* Where do we calculate the absolute capacity, which is not handled now in two
queue classes?

[~zhuqi], thank you so much for your review. [~bteke] will take over the work
from me, so [~bteke] can you continue work with [~zhuqi] to address comments?
I just uploaded ver.3 patch, fixed a potential deadlock in
AutoCreatedLeafQueue.

zhuqi commented on YARN-10504:

Thanks [~wangda] a lot.
It's my honor to work with you.
After review the YARN-10504.ver-2.patch code, i have some comments:
The change makes our logic more clear.
1. The greate change for setupConfigurableCapacities :
{code:java}
protected void setupConfigurableCapacities(
CapacitySchedulerConfiguration configuration) {
CSQueueUtils.loadCapacitiesByLabelsFromConf(getQueuePath(), queueCapacities,
configuration);
}
{code}
It's more clear here, can we just load the capacity from conf for queues,
without update absolute resources.
2. And update absolute and weight_mode(absolute) in a new Recursion ，the code
is:
{code:java}
root.updateClusterResource(csContext.getClusterResource(){code}
Based on it, we should do a lot of things.I am willing to help with it.

The patch doesn't handle auto queue creation well, so you will see some
failures which we will address them in the later revision.

Thanks [~zhuqi], as we discussed, we're working on the patch in parallel, it
will be great if you can let us know if you have intention to work on a patch
so we can coordinate in the future.
Also, as I shared offline to you, the patch you attached has the following
issues:
1) It changes CS config object, which makes hard for us to identify if it is a
change caused by config file change or internal change.
2) Auto created queue (which is why we add this feature) doesn't load config
from CS config.
I attached patch (see ver.2). It takes the following approach:
1) Major updates are in updateClusterResource, which will be called after
scheduler init and reinit.
2) Introduced new fields to QueueCapacities (weight, and normalized_weight).
Based on normalized_weight, we will calculate absolute resource.
3) Did a bunch of refactorings because code to handle changes of queue
efficient resource and config is everywhere, very hard to troubleshoot and make
further changes. I hope the refactoring in the patch can help code easier
maintained.
Can you please help to review it? [~zhuqi], [~bteke], [~pbacsko], [~shuzirra],

I added a draft patch for weight mode in CS, and need a lot of things to do.
Now i choose weight format, for example :"w:3.0", if you any advice.
Thanks.
