Subject [jira] [Commented] (YARN-1410) Handle RM fails over after getApplicationID() and before submitApplication().
Date Sat, 08 Mar 2014 13:43:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13924857#comment-13924857

Hudson commented on YARN-1410:
------------------------------

FAILURE: Integrated in Hadoop-Hdfs-trunk #1695 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1695/])
YARN-1410. Added tests to validate that clients can fail-over to a new RM
after getting an application-ID but before submission and can still submit
to the newly active RM with no issues. Contributed by Xuan Gong. (vinodkv: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1575478)

> App submission involves
> 1) creating appId
> 2) using that appId to submit an ApplicationSubmissionContext to the user.
> The client may have obtained an appId from an RM, the RM may have failed over, and the
client may submit the app to the new RM.
> Since the new RM has a different notion of cluster timestamp (used to create app id)
the new RM may reject the app submission resulting in unexpected failure on the client side.
> The same may happen for other 2 step client API operations.
