---------------------------------------
Looks like a checkin comment typo caused some commit build results to be posted
to the wrong JIRA.
> Job submission to unknown queue can leave staging directory behind
> ------------------------------------------------------------------
>
> Key: MAPREDUCE-4938
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4938
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: client
> Affects Versions: 2.0.3-alpha, 0.23.5
> Reporter: Jason Lowe
>
> There is a race where submitting a job to an unknown queue can appear to
> succeed to the client and then subsequently fail later. Since there was no
> AM ever launched, there was nothing left to cleanup the staging directory.
> At that point the client is the only thing that can cleanup the staging
> directory.
