[jira] [Created] (HIVE-14518) Support 'having' translation for Druid GroupBy queries

Jesus Camacho Rodriguez created HIVE-14518:
----------------------------------------------

             Summary: Support 'having' translation for Druid GroupBy queries
                 Key: HIVE-14518
                 URL: https://issues.apache.org/jira/browse/HIVE-14518
             Project: Hive
          Issue Type: Sub-task
          Components: Druid integration
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez


Currently, when there is a filter on top of an aggregate e.g. on the result of an aggregation function, we do not push that filter to Druid.

However, Druid supports 'having' clause for GroupBy queries, thus we should translate the Filter on top of the Aggregate and push it to Druid.
