-----------------------------------

             Summary: Vectorization: Does not handle non-column key expressions in MERGEPARTIAL
mode
                 Key: HIVE-16245
                 URL: https://issues.apache.org/jira/browse/HIVE-16245
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Critical


When the planner is able to make a column a constant, MERGEPARTIAL mode in VectorGroupByOperator
is broken because it doesn't evaluate the key expression.  One result is execution cast exception
errors.
