             Summary: Improve null handling in UDF
                 Key: TAJO-2089
                 URL: https://issues.apache.org/jira/browse/TAJO-2089
             Project: Tajo
          Issue Type: Improvement
          Components: Function/UDF
            Reporter: Jinho Kim
            Assignee: Jinho Kim
            Priority: Minor


A null value should convert to NullDatum in UDF. if not, it throw a TajoInternalError. Many
people mistake the null handling.
So we add null handling, it would be better
