> 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?
