[jira] [Created] (DRILL-834) The sum() operator should automatically promote to a type that can hold the sum

Chun Chang created DRILL-834:
--------------------------------

             Summary: The sum() operator should automatically promote to a type that can hold the sum
                 Key: DRILL-834
                 URL: https://issues.apache.org/jira/browse/DRILL-834
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Operators
            Reporter: Chun Chang
            Assignee: Mehant Baid
            Priority: Blocker


The sum() of a type may exceed the type range, hence, should implicitly and automatically promote to a type that can hold the sum. Currently, the sum just overflows into negative (see JIRA833) and gives wrong result.
