Balaji Rajagopalan commented on MAPREDUCE-1758:
-----------------------------------------------

Iyappan thanks for quick response, I agree with all of your comments, expect for 1, I don't see checking in this code will break any existing test cases, since these are new methods. I have already refactored the test cases that was using the functionality in MRcluster to JTclient. 

Jeff Herriot is a fancy name given to the system testing framework that we have developed at yahoo for hadoop mapreduce/hdfs system testing. The herriot lets the test cases be run at the system level opposed to unit testing framework which is testing the code at module level. Most of the herriot framework code for aiding this will be forwarded ported soon right now most of the work resides in yahoo internal branch.

> There is so much commonality in the test cases that we are writing, so it is pertinent to create reusable code. The common methods will be added to herriot framework.
