Josh Wills updated CRUNCH-420:
------------------------------
Attachment: CRUNCH-420.patch
So this patch makes [~aj987]'s integration test pass; basically any
materialization that divides the path between an input node and a GBK will
result in a split into two jobs: one map-only and one MapReduce.

> Reading through CRUNCH-294, it looks like materialize is supposed to function
> as a breakpoint to the planner. I've seen several plans where it appeared to
> me a particular DoFn shouldn't have been repeated, but it was.
> I'll attach some supporting material.
