Daniel Dai updated PIG-4566:
----------------------------
Attachment: PIG-4566-1.patch
Did some mass cleanup on the original patch:
1. New execution path will only kick in with "pivot" keyword
2. Limit "rollup pivot" to be the last element in cube statement
3. Lots of cleanup on the logical/physical/MR plan
Yet to do:
1. Bug fix and cleanup in the engine part
2. Port it to Tez.
