Prabhu Joseph commented on MAPREDUCE-7351:
------------------------------------------
This patch removes the _temporary directory under output path and not the
output path. And in case of job succeed or failed, even without this patch the
_temporary directory under output path will be removed.
> CleanupJob during handle of SIGTERM signal
