Subject [jira] [Commented] (YARN-1815) RM doesn't recover unmanaged AMs into its memory after restart
Date Tue, 12 Jan 2016 19:43:40 GMT

    [ https://issues.apache.org/jira/browse/YARN-1815?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15094629#comment-15094629
] 

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

I agree with [~bikassaha] that Unmanaged AM recovery should work exactly like managed AMs.
Additionally as discussed offline with [~kasha], UAMs are critical in the context of Federation
(YARN-2915) as we use UAM to transparently scale applications across multiple clusters.

[~kasha], are you planning to work on this? If not, I can take it up as I am working on Federation.
