Mark Wagner updated PIG-3527:
-----------------------------
Attachment: PIG-3527.1.patch
Here's an initial patch.There are some things that I need to clean up, and I've
made notes of these with TODOs I've posted a review at
https://reviews.apache.org/r/15194/. One interesting thing to note is that
after attaching inputs directly to the operator pipeline, I observed an ~%40
speedup. I believe this is because there aren't so many calls returning
STATUS_EOP, but I haven't tested this.

> The PigProcessor needs to be able to handle multiple distinct inputs. These
> can come in a variety of flavors including multiple "file" inputs (Merge
> join), multiple shuffle inputs (Hash Join / Co-group), and a mix (Replicated
> Join).
