Amareshwari Sriramadasu commented on HADOOP-5785:
-------------------------------------------------
bq. Also, instead of configuration, as JobSetup and JobCleanup are specified
via the job's OutPutCommitter, why not have something in the lines of the
following and use them generically to determine if a job needs setup/cleanup.
This cannot be done, because it is again user code. and we don't want to run
any user code in JobTracker.
> The job setup and cleanup tasks should be optional
