Xuan Gong commented on YARN-1521:
---------------------------------
Right now, moveApplication is only implemented for FairScheduler. We should
make sure it will be implemented as Idempotent for CapacityScheduler and verify
it works idempotent for FairScheduler when failover happens. Created
https://issues.apache.org/jira/browse/YARN-1882 to track this
> Mark appropriate protocol methods with the idempotent annotation or
> AtMostOnce annotation
