[~eyang] *yarn.rm.system-metrics-publisher.emit-container-events* is by default
false but the Documentation mentions it part of basic configuration to enable
TimelineService V2. This config can be enabled only if user requires RM
container information and not needed for enabling the Timeline Service.

Eric Yang commented on YARN-6695:
-
[~Prabhu Joseph] It looks like findbugs detected the if statement is a
contradiction to the caller that should never be null in the current location:
{code}
+ if (timelineCollector != null) {
+TimelineEntities entities = new TimelineEntities();
+entities.addEntity(entity);
+timelineCollector.putEntities(entities,
+UserGroupInformation.getCurrentUser());
+ } else {
+LOG.debug("Cannot find active collector while publishing entity "
++ entity);
+ }
{code}
It sounds like the source of NullPointerException may come from
UserGroupInformation.getCurrentUser(), where the user token has expired. Can
you confirm this?

[~Prabhu Joseph] I think another linger period flag is masking engineering
problem but not useful to system admin. Maybe we just log as debug when
NullPointerException is encountered. This will reduce the noise in log because
we know it's a race condition problem.

Prabhu Joseph commented on YARN-6695:
-
[~eyang] Thanks for checking this. Have tried below few ways to change the
ordering which improves from consistent failure to intermittent but did not
find a better way to ensure collector removal only after all events handled as
they are handled asynchronously.
1. Send ATTEMPT_FINISHED to {{RMAppImpl}} after sending APP_ATTEMPT_REMOVED to
Scheduler in {{RMAppAttemptImpl}}
2. Stop Timeline Collector as part of doneApplication in Scheduler
Another approach is to remove the collectors after a configured collector
linger period similar to YARN-3995 done for NM Events. Can you check if this
approach is fine.

Eric Yang commented on YARN-6695:
-
[~Prabhu Joseph] This fix will allow the system to continue, but it is likely
to generate more error logs due to the race condition that ATTEMPT_FINISHED
event before container is killed. Is there anything that can be done to fix
the ordering to make sure that containers are killed and finished before
ATTEMPT_FINISHED event and removes the Timeline collector last?

Prabhu Joseph commented on YARN-6695:
-
This issue happens consistently with DistributedShell job by failing container
launch. AM is finished and it has a container in {{ACQUIRED}} state.
When AM Container Finishes and final application attempt is done,
{{RMAppAttemptImpl}} sends {{RMAppEvent(ATTEMPT_FINISHED)}} to {{RMAppImpl}}
and sends {{AppAttemptRemovedSchedulerEvent}} to {{CapacityScheduler}}.
{{CapacityScheduler}} kills the live containers. By the time,
{{CapacityScheduler}} sends Kill event and then {{RMContainerImpl}} handles
Kill, {{RMAppImpl}} already handles {{ATTEMPT_FINISHED}} and removes the
Timeline Collector.
{code}
RMAppAttemptImpl -> ATTEMPT_FINISHED -> RMAppImpl#applicationFinished()
RMAppAttemptImpl -> APP_ATTEMPT_REMOVED ->
CapacityScheduler#doneApplicationAttempt() -> Kill ->
RMContainerImpl#containerFinished()

Yes this is corner case and need to handle it. We can fix this issue as I have
already reviewed patch and given comments on current patch. Secondly, it is
better to update the documentation by removing
yarn.rm.system-metrics-publisher.emit-container-events configuration in
*Enabling Timeline Service v.2*

[~rohithsharma]
I think we need to check on documentation as mentioned by [~yuan_zac]. We
should ideally cover corner cases when this flag is made true and which should
not cause any failures in RM. Thoughts ?

Zac Zhou commented on YARN-6695:
I checked the logic for TimelineServiceV2Publisher. If
yarn.rm.system-metrics-publisher.emit-container-events is set to true, RM only
publishes two events, containerCreated and containerFinished, to timeline
server v2. I think the workload is affordable.
And In the guide of TimelineServiceV2,
yarn.rm.system-metrics-publisher.emit-container-events is set to true as a
basic configuration to enable timeline v2.
This Jira is useful. I suggest to commit it to trunk recently~

[~rohithsharma] I copied the configuration from Ambari deployed cluster. You
are correct that yarn.rm.system-metrics-publisher.emit-container-events is set
to true in my cluster. Given that this would be encountered only if user
explicit set config to true. I don't think this is a 3.2.0 or 3.1.2 release
blocker, but good to fix this eventually.
Stack trace is in description of YARN-7539. I think
UserGroupInformation.getCurrentUser() returned null when YARN service does not
have a final state, and application is removed from RM memory, and unable to
get the owner of the app.

Rohith Sharma K S commented on YARN-6695:
-
[~eyang] Publishing container events from RM is disabled by default i.e
*yarn.rm.system-metrics-publisher.emit-container-events* is set to *false*. Are
you enabled this configuration? And we don't recommend to enable this
configuration since it overloads RM with lot of events. If you can attach stack
trace would be help full.
Reg the patch, I am not a fan of catching NPE! Instead lets do explicit null
check and log with right message something similar to
NMTimelinePublisher#putEntity.

Eric Yang commented on YARN-6695:
-
YARN service encounter this bug frequently because the application does not
have a completed state. The force removal of YARN service will prevent
Timeline service from publishing the finishing event. Patch 001 is a
workaround to make sure that Resource Manager doesn't crash when YARN app is
destroyed.

Yes, similar situation in YARN-8130. We should fix these race condition jiras
similar to fixes in YARN-3995 and YARN-7835.
That will also help with stack traces noted in YARN-8155
