Subject [jira] [Commented] (YARN-5556) Support for deleting queues without requiring a RM restart
Date Tue, 10 Jan 2017 18:30:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15815760#comment-15815760

Naganarasimha G R commented on YARN-5556:

Had tested the changes in the local setup, seems to be fine. Few nits which i was able to
think of were 
* "root.Q1.Q1b seems to be deleted but the queue is not yet in stopped state" error message
can be told as removed in the updated xml than deleted.
* {{"refreshQueues: java.io.IOException: Failed to re-init queues"}} is the message shown
in console though down in the stacktrace exact message is captured. Better to append the exception
message to {{"Failed to re-init queues"}} at {{CapacityScheduler.reinitialize}} on exception
* documentation needs to be updated, can either raise a new jira or add as part of this jira
for the steps to be delete the Queue in CS

Can work on this along with other comments .

> 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
