---------------------------------------
It's all yours
> History files deleted from the intermediate directory never get removed from

> Key: MAPREDUCE-5575
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5575
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver
> Affects Versions: 2.2.0
> Reporter: Sandy Ryza
>
> The JobHistoryServer periodically scans through the intermediate directory.
> It adds all files to the JobListCache. It deletes job files that are older
> than the max age and moves all other files to the done directory. Later,
> when files in the done directory become too old, they're deleted from the
> JobListCache. Jobs that were deleted in the intermediate directory (and thus
> never moved to the done directory) end up in the JobListCache but can never
> be deleted from it.
