Bikas Saha commented on YARN-628:
---------------------------------
It would have been great if we could have not had this pattern everywhere. I am
guessing the return null is there because the compiler was complaining? And the
return null is basically dead code right?
{code}
} catch (ServiceException e) {
- throw RPCUtil.unwrapAndThrowException(e);
+ RPCUtil.unwrapAndThrowException(e);
+ return null;
}
{code}

> Unwrapping of YarnRemoteExceptions (currently in YarnRemoteExceptionPBImpl,
> RPCUtil post YARN-625) is broken, and often ends up throwin
