Subject [jira] [Commented] (YARN-1879) Mark Idempotent/AtMostOnce annotations to ApplicationMasterProtocol
Date Sat, 29 Mar 2014 06:32:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-1879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13951785#comment-13951785
] 

Jian He commented on YARN-1879:
-------------------------------

Both register and unregister are checking whether the application has registered/unregistered
before. If the application has already registered/unregistered, duplicate register/unregister
attempts can cause exceptions. are they still idempotent ?
