Subject [jira] [Commented] (YARN-4839) ResourceManager deadlock between RMAppAttemptImpl and SchedulerApplicationAttempt
Date Fri, 18 Mar 2016 15:54:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-4839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15201680#comment-15201680
] 

Jason Lowe commented on YARN-4839:
----------------------------------

This appears to have been fixed as a side-effect of YARN-3361 which wasn't in the build that
reproduced this issue.  That change updated getMasterContainer to avoid locking the RMAppAttemptImpl.

> Hit a deadlock in the ResourceManager as one thread was holding the SchedulerApplicationAttempt
lock and trying to call RMAppAttemptImpl.getMasterContainer while another thread had the RMAppAttemptImpl
lock and was trying to call SchedulerApplicationAttempt.getResourceUsageReport.
