> In default, we will use multi operation when we claimQueues from ZK. But if we set hbase.zookeeper.useMulti=false, we will add a lock first, then copy nodes, finally clean old queue and the lock.
> However, if the RS acquiring the lock crash before claimQueues done, the lock will always be there and other RS can never claim the queue.
