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

             Summary: Tez and Vectorization of SUM(timestamp) not vectorized -- can't execute correctly because aggregation output is double
                 Key: HIVE-8211
                 URL: https://issues.apache.org/jira/browse/HIVE-8211
             Project: Hive
          Issue Type: Bug
          Components: Tez, Vectorization
            Reporter: Matt McCline
            Assignee: Matt McCline


Vectorization of SUM(timestamp) is currently turned off because the output of aggregation is a double (DoubleColumnVector) and the execution code is expecting a long (LongColumnVector).
