Subject [jira] [Commented] (YARN-1414) with Fair Scheduler reserved MB in WebUI is leaking when killing waiting jobs
Date Thu, 06 Feb 2014 09:36:09 GMT

    [ https://issues.apache.org/jira/browse/YARN-1414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13893208#comment-13893208
] 

Sandy Ryza commented on YARN-1414:
----------------------------------

The user string is not used to locate a leaf queue.  Instead it is used to update metrics
for resource usage of a particular user in a particular queue.  However, these metrics are
outside of the metrics hierarchy that mimics the queue hierarchy.  The argument passed to
unreserve is meant to be a leaf queue, so that the particular queue we track the resource
usage of that user in is the queue that the user's app was directly in.
