> If the job has occupied all the slots (maps and reduces), and there is kill
> from command line to kill the job, we have to make sure the cleanup task is
> eventually launched. Now there is no slot free until one of the attempts
> completes/failed.
> If there is kill from commandline during job setup, setup task has to be
> killed, before launching cleanup task.
