Suresh Srinivas commented on HADOOP-6686:
-----------------------------------------
After running a quick test, looks like in Throwable#printStackTrace(), the
first line printed is Throwable#toString(). This means the change you suggested
can be made without losing the wrapped exception info, if we add toString() to
RemoteException to print wrapped exception name.
> Remove redundant exception class name in unwrapped exceptions thrown at the
> RPC client
