> Project: Pig
> Issue Type: Wish

>
> 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.
