Josh Wills updated CRUNCH-519:
------------------------------
Attachment: CRUNCH-519-2.patch
Here's a version of this that fixes some broken tests and uses StringBuilders
for creating the label info. Two things sort of bug me-- mutable state inside
of PGroupedTableImpl to set the numreducers (I get why we need to do it, but it
bugs me), and I'd like a clearer labeling for the manual vs. automatic num
reducer messaging that isn't too wordy. [~mkwhitacre], what do you think?

> The current plan dot file display nicely the jobs, with nice names and arrows.
> However it does not explain how the planner decided on the reducers number,
> which is based on the input data size, scale factor and desired size per
> reducer.
> I suggest adding this information to the dot file.
> An addition to the DotfileWriter class can do this easily.
