Subject [jira] [Commented] (YARN-1521) Mark appropriate protocol methods with the idempotent annotation or AtMostOnce annotation
Date Wed, 26 Mar 2014 00:42:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-1521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13947399#comment-13947399
] 

Karthik Kambatla commented on YARN-1521:
----------------------------------------

Looked at the non-test source only. Looks good. One nit - it should be okay to fix at commit
time. 
# Reword to "it checks whether the application already exists"?
{code}
   * <p>During the submission process, it checks whether the application
   * has already exist. If the application exists, it will simply return
   * SubmitApplicationResponse</p>
{code}

> After YARN-1028, we add the automatically failover into RMProxy. This JIRA is to identify
whether we need to add idempotent annotation and which methods can be marked as idempotent.
