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.
