Xiao Chen commented on HDFS-9405:
-
Thanks Andrew. Will address the comments, except:
bq. Do we need this check? The sleep right before it will throw
InterruptedException and clear the interrupted status.
The reason for this is to handle {{shutdownNow}} - in which case the runnable
will be interrupted. If we happen to be not in {{Thread.sleep}} block, we
should exit. right?
bq. It looks like we're trying to ride out KMS downtime, so is there a downside
to retrying indefinitely?
I think retrying definitely would be the KISS solution. I feel configuration
won't help much for most users.
Retry interval maybe good to be configurable.
Will change into this manner if no objections.

You're right Andrew, thanks for explaining. My previous understanding is
wrong... I'll make the change shortly.

Based on my read of the [interrupt
docs|https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#interrupt()],
the idea is that we just need something in the while loop that handles the
interrupt so we can exit in a timely fashion. Both {{sleep}} and manually
checking the interrupt status achieves this. The biggest block of code where an
interrupt could come in is {{warmUpEncryptedKeys}}, and the call to {{sleep}}
right afterwards means we'll exit relatively promptly.

Thanks for the review Andrew! All comments are addressed in patch 8.
I think it's a great idea to use {{SingleThreadExecutor}} and
{{ThreadFactoryBuilder}} - it's more convenient and standardized than the
current way of hadoop {{Daemon}}.
I thought about {{waitFor}} in the test before, but since we implicitly waits
for minicluster to come up, I didn't added it. Agreed adding it makes little
harm, while strengthens the test.
BTW, haven't really think about 'retires' much, good catch. :)

A couple more review comments, otherwise looks good:
Could we use log templating for these logs?
{noformat}
NameNode.LOG.info("Warming up " + edeks.length + " EDEKs...");
...
.info("Successfully warmed up " + keyNames.length + " EDEKs.");
{noformat}
Don't need the if guard here for slf4j:
{noformat}
if (NameNode.LOG.isDebugEnabled()) {
NameNode.LOG.debug("Failed to warm up EDEKs.", ioe);
}
{noformat}
Do we need this check? The sleep right before it will throw
InterruptedException and clear the interrupted status.
{noformat}
if(Thread.currentThread().isInterrupted()) {
NameNode.LOG.info("EDEKCacheLoader thread interrupted.");
stop();
}
{noformat}
* Now that we're using the ExecutorService, I don't think we need the
{{stop()}} method and {{shouldRun}}, can just {{break}} instead?
* Can we name the thread EDEKCacheLoader so it's the same as the class?
* It looks like we're trying to ride out KMS downtime, so is there a downside
to retrying indefinitely? Another alternative is to make this configurable. If
we do indefinite retries, we'd also still want a periodic IOE print for
debugging.

A few review comments, sorry for coming into this late. Overall looks good
though, nice work here Xiao!
* Can we use an array rather than LinkedList in getAllKeyNames()? I see it gets
toArray'd later on, we can save some allocations.
* Recommend rename getAllKeyNames to just getKeyNames, unless there is a place
where we get some but not all keys
* Typo: "retiresLeft" rather than "retriesLeft"
* Have you considered using a SingleThreadExecutor to handle the thread
lifetime? Recommend also using Guava's ThreadFactoryBuilder, since you can also
give the thread a human-friendly name for nice jstack output, and also lets you
make it a daemon thread.
* In the test, should we add a waitFor in case the thread hasn't finished
filling the EDEK cache? The filling is async, so I expected some kind of
blocking/waiting for the check.

Mingliang Liu commented on HDFS-9405:
-
Thanks for updating the patch, [~xiaochen].
I was aware that we need to define variable {{spy}} again before the last
assertion. My concern was that we don't need to call {{spy()}} method against
the real object as we're not operating/mocking it. Even I'm right I have to
admit it's minor.

Thanks Arun and Mingliang for the review.
Mingliang's comments #0 and #1 are reflected in patch 4.
bq. 2. In the unit test method, is the second spy() needed?
Yes, since [Mockito
implementation|http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b27/java/lang/Class.java#2619]
copies the field.

Mingliang Liu commented on HDFS-9405:
-
Nits:
0. {{keyNames}} and {{kp}} seem final.
1. I like the idea of retrying. In the code, we log a warning message in each
retry. I think we can downgrade the log level (info or debug) while retrying.
We can log a warning message out of the while loop.
{code}
while (...) {
try {
...
return;
} catch (ioe) {
LOG.debug();
}
sleep();
}
LOG.warn();
{code}
2. In the unit test method, is the second spy() needed?

[jira] [Commented] (HDFS-9405) When starting a file, NameNode should generate EDEK in a separate thread

Thanks for the patch [~xiaochen].. gave it a fly-by..
One suggestion is to maybe retry warmup if the first attempt fails (Since the
provider might be started up later than the NN).. in the
{{EDEKCacheLoader#run}} method, in the event of an IOException, sleep and retry
a couple of times ?

-
Thanks all for the discussions and thoughts here. I'd like to work on this.
As I understand, there seems to be 2 problems:
- On NN startup/failover, the first call will trigger the {{LoadingCache}} to
fill up, which happens synchronously.
We may solve this by having a background thread to actively warm up the cache.
- If KMS or the backing key provider is down, all RPCs to create will hang and
timeout in {{FSNamesystem#startFile}} (if cache is empty).
This is arguably a bug. IMHO this should be identified at the service level,
instead of depending on the client RPC to find it.
But if we don't like the hang in the RPC, perhaps in addition to the above
background warm up, we could also update the {{ValueQueue}} to not do a get,
but a
[getIfPresent|http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/cache/Cache.html#getIfPresent(java.lang.Object)]
instead, and throw {{RetryStartFileException}} directly if nothing cached,
under the assumption that otherwise the cache should have been filled up?
Is my understanding correct?
Will work hard on making the logs/metrics helpful as well.

+1, if we have a background service for synchronous KMS operations, these would
be good things to tackle too.
I think the hardest part of all this is going to be error handling though.
Right now we get a stack trace on the client after blocking for a while, which
is pretty clear. If it's async, we'll need some new NN metrics, and also make
sure the client still has reasonable behavior and useful messages too.
RetryStartFileException is related.

Makes sense.. IIRC, we were planning on cycling through all EZ keys and calling
warmUp on each key on NN startup / failover, don't think it was done though.
Having an asnyc thread do this at startup might also make sense ?

Yup good points Arun. As you noted though, we do the initial cache warmup
synchronously, which happens when we create an encryption zone. I'd like to
move this to a background thread so it's not blocking an RPC handler if the KMS
is down. I think this same issue of blocking an RPC handler can happen in
startFile after a NN cold start or failover.

I believe the *generateEncryptedDataEncryptionKey* actually calls the
configured key provider's *generateEncryptedKey* method. If encryption is
enabled, this would generally be the *KMSClientProvider*.
The *KMSClientProvider* actually caches a bunch of EDEK when an encryption zone
is created, so for other than the first EDEK (for which is call and response
happens in the same thread) the rest of the EDEKs are actually picked from the
cache.
