> When using reflection-based Avro schemas, the default (hash-based) partitioner crashes due to GenericData.Records not being able to calculate a hash code for reflection-based data. This means that any pipeline using Avro reflection data cannot do a group by key on a PCollection (as this involves a reducer which involves the partitioner).
