Xuan Gong updated MAPREDUCE-4067:
---------------------------------
Attachment: MAPREDUCE-4067.2.patch
1. Change MRClientProtocol API to throw IOException instead of
YarnRemoteException
2. In MRClientProtocolPBClientImpl, instead of using RPCUtil.unwrap method to
unwrap and throw exceptions, we create new unwrap method to throw IOException.
3. All MR apis will not throw YarnRemoteException anymore, they will wrap
YarnRemoteException and throw out IOException instead
> Replace YarnRemoteException with IOException in MRv2 APIs

> YarnRemoteException is defined as a generic wrapper for all the exceptions in
> yarn. I think we should instead throw IOExceptions in the API, which can
> later be extended for more specialized exceptions without breaking
> compatibility.
