Subru Krishnan commented on YARN-1815:
--------------------------------------

[~jianhe], there are actually two problems I noticed while working on this:
  * With work-preserving restart in place, UAM works across RM restarts but all 
it's running containers are killed during recovery. I have a fix for this. I 
tested this with [~ellenfkh] and UAM works across RM restarts _without_ loosing 
any work.
  * We then hit the issue of UAM final state not being recorded as subsequent 
failovers of RM brings the Unmanaged apps back to _ACCEPTED_ state even though 
they had _COMPLETED_ in the past.

> RM  should record final state for unmanaged AMs
