Date Thu, 14 Nov 2013 03:27:24 GMT
Bikas Saha created YARN-1410:
--------------------------------

             Summary: Handle client failover during app submission
                 Key: YARN-1410
                 URL: https://issues.apache.org/jira/browse/YARN-1410
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha


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.
