Karthik Kambatla commented on YARN-1815:
----------------------------------------
Even if the UMA finishes successfully, there is no way for the RM to know. At
least, not until YARN-556. Today, the RM tries to recover the app, but can't
recover UAM. The corresponding RMApp transitions to FAILED after a while.
This JIRA is only avoiding those attempts to recover and marking it as FAILED
early.
> RM should recover only Managed AMs
