             Summary: Support different types for grouping columns in GroupBy Druid queries
                 Key: HIVE-16751
                 URL: https://issues.apache.org/jira/browse/HIVE-16751
             Project: Hive
          Issue Type: Bug
          Components: Druid integration
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Calcite 1.13 pushes EXTRACT and FLOOR function to Druid as an extraction function (cf CALCITE-1758). Originally, we were assuming that all group by columns in a druid query were of STRING type; however, this will not true anymore (result of EXTRACT is an INT and result of FLOOR a TIMESTAMP).

When we upgrade to Calcite 1.13, we will need to extend the DruidSerDe to handle these functions.
