             Summary: CBO: Calcite Operator To Hive Operator (Calcite Return 
Path): ColumnPruner prunes columns of UnionOperator that should be kept
                 Key: HIVE-11333
                 URL: https://issues.apache.org/jira/browse/HIVE-11333
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


unionOperator will have the schema following the operator in the first branch. 
Because ColumnPruner prunes columns based on the internal name, the column in 
other branches may be pruned due to a different internal name from the first 
branch. To repro, run rcfile_union.q with return path turned on.
