Siddharth Seth updated YARN-628:
--------------------------------
Attachment: YARN-628.txt
The patch makes the following changes
- Changes RPCUtil.unwrapAndThrowException to throw IOException and
YarnRemoteException.
- Fixes the implementation of this Unwrap method.
- Removed references to UndeclaredThrowableException from YARN tests.
- Adds unit tests for RPCUtil.unwrapAndThrowException
unwrapAndThrowException was earlier returning an exception. This has been
changed to throw an exception instead - seems like a cleaner approach since
individual PBClientImpls don't need an additional check on the exception type
before throwing. It does introduce this strange bit of code in all PBImpls
'return null', which will never be executed.
