> Locking and exception issues in JobHistory Server.
> --------------------------------------------------
>
> Key: MAPREDUCE-3972
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3972
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv2
> Affects Versions: 0.23.2
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Attachments: MR-3972.txt, MR-3972.txt, MR-3972.txt, MR-3972.txt

>
> The JobHistory server's locking is inconsistent and wrong in some cases.
> This is not super critical because the issues would only show up if a job is
> being cleaned up or moved from intermediate done to done, at the same time it
> is being parsed into a CompletedJob. However the locking is slowing down the
> server in some cases, and is a ticking time bomb that needs to be addressed.
> As part of this too we need to be sure that the Cleaner and Intermediate to
> Done migration threads handle exceptions properly. Now it appears that the
> exception is logged, and the thread just shuts down. This means that the
> history server could still be up and running for weeks and never remove old
> jobs.
