Subject [jira] [Commented] (YARN-6020) Resource.add exceed Int boundary,when compute queue demand in FairScheduler
Date Tue, 28 Mar 2017 18:19:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15945663#comment-15945663

Daniel Templeton commented on YARN-6020:
----------------------------------------

Looks to me like the reason your patch is failing is that you have a local commit in your
tree.  If you run "git status", does it tell you that your local repo is "ahead of 'apache/hadoop'
by <n> commits"?
