Amareshwari Sriramadasu commented on HADOOP-4361:
-------------------------------------------------
During the cleanup, (the time JT is waiting for the cleanup to get launched,
and while cleaning up), the JobStatus should be "CLEANUP". This makes the tasks
get KillTaskAction immediately and makes slots free. Thoughts?

> 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.
