Vinod Kumar Vavilapalli commented on MAPREDUCE-4067:
----------------------------------------------------
Revisiting this.
I think we are on the correct patch. We should just replace the
YarnRemoteException with IOException in all of MR protocols. Clearly the legacy
MR clients don't know or care about YarnRemoteExceptions.

> YarnRemoteException is defined as a generic wrapper for all the exceptions in
