Sean Owen commented on MAHOUT-781:
----------------------------------

Xiaobo, the process is that you first explain what you are trying to 
accomplish, then propose a patch, then it is reviewed, and then it is 
committed. I think you have skipped the first step.

Where does this become useful to Mahout? I can sort of imagine it as a utility 
class, but not in core.
What is test-data.zip?
Is there a need to preserve line number in the output? seems like no reducer is 
needed.
