Abhishek Kapoor commented on YARN-69:
-------------------------------------

Sorry If I am little behind, but it looks like in release 2.0.5 alpha new exceptions are introduced
YarnException and IOException. Are still thinking to introduce more exceptions as described
above ?

> We should distinguish the exceptions for absent app/node/queue, illegally accessed app/node/queue
etc. Today everything is a {{YarnRemoteException}}. We should extend {{YarnRemoteException}}
to add {{NotFoundException}}, {{AccessControlException}} etc. Today, {{AccessControlException}}
exists but not as part of the protocol descriptions (i.e. only available to Java).
