Subject [jira] [Commented] (YARN-4785) inconsistent value type of the "type" field for LeafQueueInfo in response of RM REST API - cluster/scheduler
Date Wed, 16 Mar 2016 06:44:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-4785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15196881#comment-15196881
] 

Varun Vasudev commented on YARN-4785:
-------------------------------------

Thanks for the review [~djp]. I think there's definitely some JAXB implementation issue here.
The test will fail on branch-2.6, branch-2.7 and passes in branch-2.8, branch-2 and trunk.
