Jian He commented on MAPREDUCE-5471:
------------------------------------
bq. The same AM cannot have stop and start logs, right?
That logs may indicate that MR fails in the starting phase because the staging
dir is cleaned by the first completed AM, and immediately stops after that.
> Succeed job tries to restart after RMrestart
