Bugs: PIG-4766
https://issues.apache.org/jira/browse/PIG-4766
Repository: pig-git
Description
-------
PIG-4709 introduced Combiner optimization for Group By. However, the patch did
not handle cases where constant/conditional expressions were used. It also did
not handle limit.
This patch is to address those gaps.
