> YARN Preemption Monitor got java.util.ConcurrentModificationException when
> three or more partitions exists
> ----------------------------------------------------------------------------------------------------------
>
> Key: YARN-10892
> URL: https://issues.apache.org/jira/browse/YARN-10892
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 3.1.2
> Reporter: Jeongin Ju
> Priority: Major
> Attachments: YARN-10892.001.patch
>
>
> On our cluster with a large number of NMs, preemption monitor thread
> consistently got java.util.ConcurrentModificationException when specific
> conditions met. (And preemption doesn't work, of course)
> What We found as conditions are as follow. (All 4 conditions should be met)
> # There are at least two non-exclusive partitions except default partition
> (let me call the partitions as X and Y partition)
> # app1 in the queue belonging to default partition (let me call the queue as
> 'dev' queue) borrowed resources from both X, Y partitions
> # app2, app3 submitted to queues belonging to each X, Y partition is
> 'PENDING' because resources are consumed by app1
> # Preemption monitor can clear borrowed resources from X or Y when the
> container of app1 is preempted.
> Main problem is that FifoCandiatesSelector.selectCandidates tried to remove
> HashMap key(partition name) while iterating HashMap.
> Logically, it is correct because we didn't traverse the same partition again
> on this 'selectCandidates'. However HashMap structure does not allow
> modification while iterating.
> I made test case to reproduce the error
> case(testResourceTypesInterQueuePreemptionWithThreePartitions).
> We found and patched our cluster on 3.1.2 but it seems trunk still has the
> same problem.
> I attached patch based on the trunk.
>
> Thanks!
