Subject [jira] [Commented] (YARN-5562) [Atsv2] system entities retrieval in REST throws NPE
Date Thu, 25 Aug 2016 13:00:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-5562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15436806#comment-15436806

Varun Saxena commented on YARN-5562:
------------------------------------

This is similar to YARN-4220.
I think we can close either one of the JIRA. As Li is on leave, maybe you can assign that
JIRA to yourself or close that one.
