---------------------------------------
Summary: UnionOptimizer hits errors when merging vertex group into
split
Key: PIG-4769
URL: https://issues.apache.org/jira/browse/PIG-4769
Project: Pig
Issue Type: Bug
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: 0.16.0
1) For a script that needs store vertex group removed and merged into split,
it gives error
Caused by: java.lang.IllegalArgumentException: VertexGroup must have at least 2
members
as we leave the vertexgroup with just one member in it (POSplit).
2) For a script that needs non-store vertex group removed, it gives error
Input from vertex scope-xxx is missing
In this case, vertex group is removing but successor inputs are not replaced
correctly.
