PERFORMANCE: not creating bags for ORDER BY
-------------------------------------------
Key: PIG-802
URL: https://issues.apache.org/jira/browse/PIG-802
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
Order by should be changed to not use POPackage to put all of the tuples in a
bag on the reduce side, as the bag is just immediately flattened. It can
instead work like join does for the last input in the join.
