> As an example, if a flow file containing an Avro record consisting of an array of structs/records, ConvertAvroToORC will appear to successfully convert the flow file, but the array will contain null values (as seen from Hive when querying a table atop the ORC file(s) ).
> If Maps are the underlying object supporting records in the Avro file, this works fine; however often (especially if using ConvertJsonToAvro), the object will be a GenericData.Record. If so, this record should be parsed like a Map (i.e. named fields), an OrcStruct generated, etc.
