> If the master is dispatching a RPC call to RS when aborting. A connection
> exception may be thrown by the RPC layer(A IOException with "Connection
> closed" message in this case). The RSProcedureDispatcher will regard is as an
> un-retryable exception and pass it to UnassignProcedue.remoteCallFailed,
> which will expire the RS.
> Actually, the RS is very healthy, only the master is restarting.
> I think we should deal with those kinds of connection exceptions in
> RSProcedureDispatcher and retry the rpc call
