             Summary: Consider writing to both ats v1 & v2 from RM for smoother upgrades
                 Key: YARN-6736
                 URL: https://issues.apache.org/jira/browse/YARN-6736
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vrushali C



When the cluster is being upgraded from atsv1 to v2, it may be good to have a brief time period during which RM writes to both atsv1 and v2. This will help frameworks like Tez migrate more smoothly.
