UnionOperator fails when different inputs have different ObjectInspector (but
the same TypeInfo)
------------------------------------------------------------------------------------------------
Key: HIVE-635
URL: https://issues.apache.org/jira/browse/HIVE-635
Project: Hadoop Hive
Issue Type: Bug
Affects Versions: 0.3.0, 0.3.1
Reporter: Zheng Shao
Assignee: Zheng Shao
The current UnionOperator code assumes the ObjectInspectors from all parents
are the same.
But in reality, they can be different, and UnionOperator needs to do conversion
if necessary.
