Vinod Kumar Vavilapalli commented on YARN-1882:
-----------------------------------------------
>From my quick glance of YARN-1521 patch, it seemed like the move itself is
>never recorded in the state-store. That is a pre-requisite to make it work
>across fail-over.
> Implement and verify Scheduler#moveApplication() idempotent for
> CapacityScheduler/FairScheduler

> After YARN-1521, we have marked
> ApplicationClientProtocol#moveApplicationAcrossQueues as Idempotent. We
> should make sure:
> * In CapacityScheduler, it is implemented as idempotent
> * In FairScheduler, verify it works idempotent when failover happens
