Subject [jira] [Commented] (YARN-4934) Reserved Resource for QueueMetrics needs to be handled correctly in few cases
Date Sat, 09 Apr 2016 06:10:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-4934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15233383#comment-15233383

Sunil G commented on YARN-4934:
-------------------------------

After analysis I found that this issue is not related to the fix made by this patch or earlier
rather its a timing issue. YARN-4890 is tracking this problem and a patch is shared there.

Other webservices failures are due to "Address already in use" pblm. YARN-4909 is tracking
this sporadic issue. Other issues are know pblms due to DNS.
