Subject [jira] [Updated] (YARN-2062) Too many InvalidStateTransitionExceptions from NodeState.NEW on RM failover
Date Mon, 29 Dec 2014 00:14:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-2062?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated YARN-2062:
-----------------------------------
    Attachment: yarn-2062-1.patch

Straight-forward patch that adds a dummy transition to not log invalid transitions. 

[~jianhe], [~adhoot] - does this patch make any sense? Should we be handling all these transitions
to better handle work-preserving RM restart?
