Mark Wagner updated PIG-3591:
-----------------------------
Attachment: PIG-3591.1.patch
Separate "packaging" logic from "shuffle handling" logic. This moves the
packaging logic to a new class "Packager", which is extended by
CombinePackager, LitePackager, MultiQueryPackager, and JoinPackager.
This is not finished. Known problems are illustrate and streaming the last
input are not implemented.
> Refactor POPackage to separate MR specific code from packaging

> POPackage is currently closely associated with the MR shuffle semantics. This
> makes it difficult to adapt the variety of subclasses of POPackage to other
> execution engines without duplicating code.
