Subject [jira] [Created] (CRUNCH-13) Partitioner crash in pipelines containing reflection-based Avro data

----------------------------------

             Summary: Partitioner crash in pipelines containing reflection-based Avro data
                 Key: CRUNCH-13
                 URL: https://issues.apache.org/jira/browse/CRUNCH-13
             Project: Crunch
          Issue Type: Bug
    Affects Versions: 0.3.0
            Reporter: Gabriel Reid
            Assignee: Gabriel Reid


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).
