             Summary: Add flag to allow approximate results coming from Druid
                 Key: HIVE-16121
                 URL: https://issues.apache.org/jira/browse/HIVE-16121
             Project: Hive
          Issue Type: Improvement
          Components: Druid integration
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Druid allows approximate results for some kind of operations and queries (count distinct, top n, decimal type, ...). There are some flags in Calcite to control this behavior; we should expose these flags in Hive so user can set their value.
