Xuan Gong commented on YARN-142:
--------------------------------

Split it into several sub-tasks:
1. Make YarnRemoteException not be rooted at IOException
2. change AMRMProtocol api to throw IOException and YarnRemoteException
3. change ClientRMProtocol api to throw IOException and YarnRemoteException
4. change ContainerManager api to throw IOException and YarnRemoteException
5. change RMAdminProtocol api to throw IOException and YarnRemoteException

> All YARN APIs currently throw YarnRemoteException.
> 1) This cannot be extended in it's current form.
> 2) The RPC layer can throw IOExceptions. These end up showing up as UndeclaredThrowableExceptions.
