[jira] [Created] (DRILL-360) Enhance HashFunctions to handle null values
Aman Sinha created DRILL-360:

             Summary: Enhance HashFunctions to handle null values
                 Key: DRILL-360
                 URL: https://issues.apache.org/jira/browse/DRILL-360
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Aman Sinha
Currently, the HashFunctions class uses the NullHandling semantics of NULL_IF_NULL which means it will produce null value for a null input.  In order for Drill operators that perform hashing to work correctly with null inputs, we need to add appropriate handling in the HashFunctions such that they produce integer values (e.g 0) for such inputs.
