Review request for pig and Daniel Dai.
Bugs: PIG-5118
https://issues.apache.org/jira/browse/PIG-5118
Repository: pig
Description
-------
The current code of splitting DAG does not handle cases where there is split
and a clean segmentation is not possible. It also does not handle cases where
there is multiple segments and they are later used together. Both cases it ends
up with "Invalid dag containing 0 vertices" error as it creates one empty DAG
and and a new DAG which contains the full original plan as it was not able to
segment.
