Subject [jira] [Commented] (YARN-5556) Support for deleting queues without requiring a RM restart
Date Sat, 07 Jan 2017 01:57:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15806480#comment-15806480

Naganarasimha G R commented on YARN-5556:
-----------------------------------------

Thanks [~wangda] & [~xgong], 
bq. I think we don't need the additional DELETED state, first it generate some maintenance
overheads, for example we need to maintain state transition to/from of the DELETED state.
And since by design a queue can be deleted only if queue is stopped and no app running, so
the impact of typo should be minimum. Our preference is simply remove queue from config.
This makes the things pretty clear and straight forward for users/admin, and clears all my
queries. Will modify and upload the patch at the earliest.

> Today, we could add or modify queues without restarting the RM, via a CS refresh. But
for deleting queue, we have to restart the ResourceManager. We could support for deleting
queues without requiring a RM restart
