Doug Cutting commented on MAPREDUCE-815:
----------------------------------------
> That having been said, we can't use null or we'll break the identity mapper.
It seems to me that we should be able to pass null end-to-end as a value. If
we can't, then we perhaps haven't yet removed all of the Writable assumptions,
no?
> Add AvroInputFormat and AvroOutputFormat so that hadoop can use Avro
> Serialization
