> 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.
