> Key: MAPREDUCE-1841
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1841
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: task
> Affects Versions: 0.20.2
> Reporter: Arun C Murthy
> Assignee: Arun C Murthy
>
> o.a.h.mapred.FileOutputCommitter.getWorkOutputPath checks for existence of
> ${mapred.output.dir}/_temporary to ensure tasks launched _after_ the
> job-cleanup task fail early (in a vast majority of cases). This check is
> missing in the mapreduce libraries.
> Related note: FileOutputCommitter.setupTask seems a more appropriate place
> for the above check...
