Vinod K V commented on HADOOP-5785:
-----------------------------------
i think it should be job specific as we specify setup/cleanup via
OutputCommitter which itself is job specific.
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.
{code}
OutputCommitter.isJobSetupNeeded()
OutputCommitter.isJobCleanupNeeded()
{code}
Thoughts?
> The job setup and cleanup tasks should be optional
