Dfs methods should not throw RemoteException
--------------------------------------------
Key: HADOOP-2841
URL: https://issues.apache.org/jira/browse/HADOOP-2841
Project: Hadoop Core
Issue Type: Improvement
Components: dfs
Affects Versions: 0.16.0
Reporter: Hairong Kuang
Fix For: 0.17.0
Dfs should unwrap the RemoteException and throw the real cause of the error to
the user. This allows the user to find out the real cause without examining the
remote exception. This also allows the user to use the dfs interface without
aware of the implementation details (i.e. rpc).
