-----------------------------------------------------

             Summary: Avro file format's support for map and nullable union data types.
                 Key: DRILL-3458
                 URL: https://issues.apache.org/jira/browse/DRILL-3458
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Other
    Affects Versions: 1.0.0
            Reporter: Bhallamudi Venkata Siva Kamesh
            Assignee: Jacques Nadeau


Avro file format as of now does not support union and map datatypes.
For union datatypes, like [Pig|https://cwiki.apache.org/confluence/display/PIG/AvroStorage]
and [Hive|https://cwiki.apache.org/confluence/display/Hive/AvroSerDe], I think, we can support
nullable union like ["null", "some-type"].
