Status: Open (was: Patch Available)
> Potential ResourceManager deadlock when SchedulerEventDispatcher is stopped
> ---------------------------------------------------------------------------
>
> Key: MAPREDUCE-4139
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4139
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.3
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: MAPREDUCE-4139.patch, MAPREDUCE-4139.patch

>
> When the main thread calls ResourceManager$SchedulerEventDispatcher.stop() it
> grabs a lock on the object, kicks the event processor thread, and then waits
> for the thread to exit. However the interrupted event processor thread can
> end up trying to call the synchronized getConfig() method which results in
> deadlock.
