> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.2
> Reporter: Alexandre Normand
> Assignee: Alexandre Normand
> Labels: java, newbie

> When setting up a map/reduce job with the AvroKeyValueOutputFormat, using Reflection to create the schema and AvroValue to wrap the data objects to serialize, I get a ClassCastException because the datum is the object and not an instance of IndexedRecord.
> I think that AvroKeyValueRecordWriter should create a {{ReflectDatumWriter}} much like AvroKeyRecordWriter does instead of a {{GenericDatumWriter}}, right?
