Subject [jira] [Commented] (YARN-1872) TestDistributedShell occasionally fails in trunk
Date Fri, 27 Jun 2014 05:59:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-1872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14045574#comment-14045574

Hong Zhiguo commented on YARN-1872:
-----------------------------------

Hi,  Vinod, this is not just a test failure. It occurs frequently in out real cluster. When
this happens, the application remains running forever until it's killed manually.

And I don't think the fix is just a work around before YARN-1902 get in. It makes DistributedShell
taking less assumption about outside, and more tolerant to unexpected behavior of outside.
