Alexandre Normand updated AVRO-1162:
------------------------------------

    Labels: java newbie  (was: )
    Status: Patch Available  (was: Open)

I've tested with this patch that just changes GenericDatumWriter to ReflectDatumWriter in
AvroKeyValueRecordWriter.

> 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?
