- 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

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.
