-----------------------------------------------------
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"].
