      Description

      We might need to prioritize DN RPC over client RPC so that no matter what application do to NN RPC and FSNamesystem's global lock, DN's requests will be processed timely. After a cluster is configured to have service RPC server separated from client RPC server, it is mitigated to some degree with fair FSNamesystem's global lock. Also if the NN global lock can be made more fine grained; such need becomes less important. Still, it will be good to evaluate if this is a good option.
