Subject [jira] [Updated] (YARN-1558) After apps are moved across queues, store new queue info in the RM state store
Date Sat, 04 Jan 2014 20:13:50 GMT

     [ https://issues.apache.org/jira/browse/YARN-1558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sandy Ryza updated YARN-1558:
-----------------------------

    Description: 
The result of moving an app to a new queue should persist across RM restarts.  This will require
updating the ApplicationSubmissionContext, the single source of truth upon state recovery,
with the new queue info.

There will be a brief window after the move completes before the move is stored.  If the RM
dies during this window, the recovered RM will include the old queue info.  Schedulers should
be resilient to this situation.
