Ido Hadanny commented on PIG-3117:
----------------------------------

[~cheolsoo] - thanks, looks great. 
One question: for TestRemoveIntermediateResults.tearDown you used the Before annotation, maybe you meant "After" (Or instead of tearDown you meant to use setUp)?

> when we debug our pig jobs on pre-production data, we usually find bugs we couldn't detect in our UT, as env and data are not quite the same.
> when the final output of a script is not quite what we expect, we start divide-and-conquer, running it line by line and inspecting the intermediate output of each stage. 
> It would be great if we could simply configure pig not to delete the intermediate MR outputs, and store them as plaintext instead of snappy format.
