Subject [jira] [Commented] (YARN-5556) Support for deleting queues without requiring a RM restart
Date Tue, 08 Nov 2016 00:30:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15645950#comment-15645950

Wangda Tan commented on YARN-5556:
----------------------------------

Thanks [~Naganarasimha], 

I'm OK with pulling YARN-5761 into branch-2.8 (assume this patch will build on top of YARN-5761).

Some comments:
1) Verify no app running is not enough -- we need also check queue is in stopped state. so
I think YARN-5746 is required for this patch.
2) {{removeChildQueue}} should be method of ParentQueue only.

So I think it's better to wait YARN-5746 / YARN-5761 committed before working on this patch.
Which should happen soon.

Thoughts?

> 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
