Jian He commented on YARN-1815:
-------------------------------
bq. The completion information is saved, except for those AMs that finish while
the RM is down.
The completion information for Unmanaged AMs is not saved. UnmanagedAM
transition path is different from normal AM. The right fix should be to record
the UnmanagedAM completion info also.
> RM doesn't recover unmanaged AMs into its memory after restart
