Subject [jira] [Commented] (YARN-1815) RM should recover only Managed AMs
Date Wed, 19 Mar 2014 22:14:43 GMT

    [ https://issues.apache.org/jira/browse/YARN-1815?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13941073#comment-13941073
] 

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.
