[jira] [Commented] (YARN-3362) Add node label usage in RM CapacityScheduler web UI

["Wangda Tan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-3362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14507949#comment-14507949 ] 

Wangda Tan commented on YARN-3362:
----------------------------------

Since this patch tends to create a new RM web view, so I suggest to do it in a compatible way so that people will not get lost when using the new view: 
- When label is not enabled in the cluster or there's only "default" label, it will not show the "label-hierarchy", so it will be very similar to what we have in old RM web UI
- All queue's capacities and usages (by partition) can be found in CSQueue.getQueueCapacities/getQueueResourceUsages.
- We may not need to consider show app-by-partition with this patch. Filter apps in a queue by partition needs add additional CS interface, which should be addressed in a separated patch.

> 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.
