> ConvertAvroToORC doesn't handle records/structs nested in other objects
> -----------------------------------------------------------------------
>
> Key: NIFI-2593
> URL: https://issues.apache.org/jira/browse/NIFI-2593
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Fix For: 1.0.0
>
>
> 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.
