Description

Hive Processors that use UserGroupInformation objects to perform operations with a given identity use the ugi.doAs() method to do so. This method can throw an UndeclaredThrowableException wrapping the actual exception if it isn't one of a few specific exceptions.

We need to unwrap the exception and throw the cause in the same way as the non-ugi code in order to maintain consistent behavior.
