Tsz Wo (Nicholas), SZE commented on HADOOP-2431:
------------------------------------------------
In NameNode, AccessControlException is thrown directly. RPC wraps it as a
RemoteException. So client gets a RemoteException (wrapping
AccessControlException).
The situation is similar for other IOException like "Cannot open filename".
Shell we unwrap "Cannot open filename"? If yes, then it is better to modify
RPC.
