Subject [jira] [Commented] (YARN-1879) Mark Idempotent/AtMostOnce annotations to ApplicationMasterProtocol
Date Sun, 05 Oct 2014 22:32:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-1879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14159730#comment-14159730
] 

Xuan Gong commented on YARN-1879:
---------------------------------

+1 on Jian's proposal. We need to handle this scenario in failover/restart. But the Retry-cache
method can not fully solve this problem. Handling it on RM side sounds like a better idea.
We did similar things before, such as submitApplication.
