--------------------------------
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.
