Benoy Antony updated HADOOP-9939:
---------------------------------
Attachment: hadoop-9939.patch
Attaching a patch to accomplish the custom error processing requirement.
An Interface - CustomExceptionHandler is defined. Control is given to this
CustomExceptionHandler from different exception blocks. The exception blocks
are identified by a handle.
A DefaultCustomExeptionHandler is defined to keep the default exception
handling for each error case.
The framework is used when an Authentication failure occurs.
A testcase is written to test the exceptionHandler.
