Grant Ingersoll updated MAHOUT-904:
-----------------------------------
Attachment: MAHOUT-904.patch
Converts SplitInput to use AbstractJob.
I think this is pretty close to being ready. I wonder if there is more
opportunity for overlap between the sequential and the m/r version, but we can
iterate on that later if people want.
> SplitInput should support randomizing the input

> For some learning tasks, we need the input to be randomized (SGD) instead of
> blocks of labels all at once. SplitInput is a useful tool for setting up
> train/test files but it currently doesn't support randomizing the input.
