Subject [jira] [Commented] (YARN-845) RM crash with NPE on NODE_UPDATE
Date Mon, 17 Jun 2013 21:10:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13685988#comment-13685988
] 

Arpit Gupta commented on YARN-845:
----------------------------------

Mayank

Unfortunately cannot consistently reproduce this. We saw this on a cluster where pig e2e tests
were running and started failing because the RM went down. On other nights and other clusters
the same set of tests have gone through without any issues.
