Major Description
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?
