Doug Cutting commented on HADOOP-2431:
--------------------------------------
Perhaps if the exception named in the RemoteException is a class that's loaded
on the client and is permitted by the method signature, then RPC should
automatically try to construct an instance and throw it. But that's not what
RPC does today. If you feel it should do this, please file a separate issue.
The FileSystem API promises that applications which attempt to violate
permissions will be thrown an AccessControlException. Today, until RPC is
changed, we must intercept RemoteException and explicitly throw an
AccessControlException. The fact that a particular FileSystem is implemented
using RPC should be invisible to clients.
