Subject [jira] [Commented] (YARN-3362) Add node label usage in RM CapacityScheduler web UI
Date Sun, 10 May 2015 14:08:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-3362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14537183#comment-14537183
] 

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

Also few suggestions in UI :
* Earlier over all available resource info was available in cluster metrics and hence i think
it was easier for viewer to relate the percentages but here available resource info for a
given label is present only in nodelabels page. so i would suggest to have label resource
info  like :
{code}
+ Partition: xxx [memory:8192, vCores:8]
  + Queue: root
     + Queue: a
     + Queue: b
+ Partition: yyy [memory:4096, vCores:8]
  + Queue: root
     + Queue: a
     + Queue: b
{code}
* I think queue hierarchy is not always helpful when i want to relatively compare capacities
among leaf queue (through bars), so i would suggest additional view without queue hierarchy
when user clicks on a button [ kind of toggle button].
{code}
                -------------------
                | Hide Hierarchy |
                -------------------
+ Partition: xxx [memory:8192, vCores:8]
  + Queue Path: root.Q1.a
    ....
  + Queue Path: default
+ Partition: yyy [memory:4096, vCores:8]
  + Queue Path: root.Q1.a
    ....
  - Queue Path: default
       |---------  Partition Specific Metrics -----------|
       |                 ........                        |
       |-------------------------------------------------|
       |---------  Queue General Metrics ----------------|
       |                 ........                        |
       |-------------------------------------------------|
       Active user info:
       ........ Table ..........
{code}

> 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.
