Subject [jira] [Commented] (YARN-4624) NPE in PartitionQueueCapacitiesInfo while accessing Schduler UI
Date Fri, 29 Jul 2016 08:41:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-4624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15398970#comment-15398970
] 

Sunil G commented on YARN-4624:
-------------------------------

Yes [~Naganarasimha Garla]. We need to make some progress here, as its a long pending task.

v3 patch comes with a find bugs issue. We do type conversion from to box type two times and
causing this problem. I think we can go with v1 patch itself to resolve the issue for now.
Improvement to hide some non-used items can be done in an another improvement jira. Thoughts?.

Also patch might need a rebase, [~brahmareddy], could you please help to rebase once v1 or
v3 is decided. If you are busy, i could also help to do the same.
