Subject [jira] [Commented] (YARN-2561) MR job client cannot reconnect to AM after NM restart.
Date Wed, 17 Sep 2014 17:25:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14137590#comment-14137590

Junping Du commented on YARN-2561:

Thanks [~jlowe] for the comments! Yes. Checking running containers reported by NM seems to
be a better way given each NM's recovery configuration is possible to be different (although
we don't encourage this configuration. Isn't it?). v3 patch use the new way.
