Bikas Saha commented on YARN-529:
---------------------------------

By 1) you mean let RM accept finishApplicationAttempt() from the last attempt?

> MR app master will clean staging dir, if the job is already succeeded and asked to reboot.
If the finishApplicationMaster call fails, RM will consider this job unfinished and launch
further attempts, further attempts will fail because staging dir is cleaned
