[jira] [Commented] (YARN-589) Expose a REST API for monitoring the fair scheduler

    [ https://issues.apache.org/jira/browse/YARN-589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13642305#comment-13642305 ] 

Sandy Ryza commented on YARN-589:
---------------------------------

Attached xml output from a first cut at this.  Is it missing anything?  Any opinions on whether outputting the whole thing as one chunk (as the capacity scheduler does) rather than making metrics available for individual queues at different URLs is a bad idea?
