Subject [jira] [Commented] (YARN-3362) Add node label usage in RM CapacityScheduler web UI
Date Mon, 18 Apr 2016 13:01:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-3362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15245610#comment-15245610

Eric Payne commented on YARN-3362:

- When i submit a app to a queue with default node label expression set to a partition then
in the scheduler page stats was not getting displayed.

Other issues which are good to be backported :
# i think there is one other jira which was capturing the queue's default node label expression
that would also be helpful to be back ported
# App's AM's label is also good to be captured in the web ui and displayed.
# would it be good to back port MAPREDUCE-6304 ?

[~Naganarasimha], thank you very much for your review and comments.

I'm sorry I did not make it clear in this JIRA. Please refer to conversations in YARN-4751
between me, [~leftnoteasy], and [~sunilg].

The problem is that in order to provide all of the needed functionality in 2.7, we either
have to backport several JIRAs which would destabilize 2.7 (please see [this comment|https://issues.apache.org/jira/browse/YARN-4751?focusedCommentId=15218335&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15218335]
and [this comment|https://issues.apache.org/jira/browse/YARN-4751?focusedCommentId=15219358&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15219358])
 or we need to pick and choose pieces to backport without doing full cherry-picks. 

After the discussion in YARN-4751, we thought it would be best to submit a 2.7 patch here
that only backported YARN-3362 and then add the fixes for the metrics in YARN-4751. Please
let me know what you think.

will be hard to understand what happened to nodes have labels assign to it.
