> Key: DRILL-3458

> 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"].
