[jira] [Commented] (YARN-1815) RM doesn't recover unmanaged AMs
into its memory after restart
[ 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.
