Subject [jira] [Commented] (YARN-3362) Add node label usage in RM CapacityScheduler web UI
Date Wed, 13 May 2015 16:02:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-3362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14542151#comment-14542151
] 

Naganarasimha G R commented on YARN-3362:
-----------------------------------------

Thanks for the comment [~Wangda],
This idea is also good but i can think of few issues here 
* In most cases Queue hierarchy will be collapsed so the space between non leaf queue name
and the bar might not look good 
* Bigger the name of the leaf queues more space between the queue name and the bar (at the
upper level queues)
* Space based calculation might not work out so implementing it with Hammock might be little
complex. 
* Here were you thinking of publishing absolute usage or usage @ queue level, I feel absolute
usage would be better (YARN-3638 also suggest it), but existing shows just usage @ queue level.

Also i feel these modifications can take time, if this jira is important then we can push
this in and we can further discuss about UI enhancements in another jira. thoughts?

> We don't have node label usage in RM CapacityScheduler web UI now, without this, user
will be hard to understand what happened to nodes have labels assign to it.
