Subject [jira] [Commented] (YARN-1879) Mark Idempotent/AtMostOnce annotations to ApplicationMasterProtocol
Date Sat, 29 Mar 2014 06:07:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-1879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13951779#comment-13951779
] 

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

ApplicationMasterService#registerApplicationMaster does have the lastResponse stuff. So, I
think that it is OK for us to add the annotation in this ticket.

ApplicationMasterService#finishApplicationMaster is to submit RMAppAttemptUnregistrationEvent,
and check status. So, adding idempotent annotation is OK, too

So, we can fix three of APIs together in this ticket.
Mark
* allocation --> AtMostOnce
* registerApplicationMaster --> Idempotent
* finishApplicationMaster --> Idempotent
