> MR AM to clean up temporary files from previous attempt
> -------------------------------------------------------
>
> Key: MAPREDUCE-6984
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6984
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: applicationmaster
> Affects Versions: 3.0.0-beta1
> Reporter: Gergo Repas
> Attachments: MAPREDUCE-6984.000.patch, MAPREDUCE-6984.001.patch
>
>
> When the MR AM restarts, the
> {outputDir}/_temporary/{appAttemptNumber} directory
> remains on HDFS, even though this directory is not used during the next
> attempt if the restart has been done without recovery. So if recovery is not
> used for the AM restart, then the deletion of this directory can be done
> earlier (at the start of the next attempt). The benefit is that more free
> HDFS space is available for the next attempt.
