Subject [jira] [Commented] (YARN-4328) Findbugs warning in resourcemanager in branch-2.7 and branch-2.6
Date Tue, 01 Dec 2015 08:13:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15033309#comment-15033309

Akira AJISAKA commented on YARN-4328:
-------------------------------------

I'm thinking it's okay to add a section in findbugs-exclude.xml to fix the below warning.
{noformat}
<file classname='org.apache.hadoop.yarn.server.resourcemanager.scheduler.SchedulerApplicationAttempt'>
<BugInstance type='IS2_INCONSISTENT_SYNC' priority='Normal' category='MT_CORRECTNESS' message='Inconsistent

{noformat}
In branch-2.7, there is a section to ignore the warning, added by YARN-2938.
I'll attach a patch for branch-2.6 shortly.
