> When using Avro data as the output key/values of a MapReduce job with TextOutputFormat,
you get output that looks like:
> {code:none}
> org.apache.avro.mapred.AvroKey@1f62000	org.apache.avro.mapred.AvroValue@1
> org.apache.avro.mapred.AvroKey@1fe8c4a	org.apache.avro.mapred.AvroValue@1
> org.apache.avro.mapred.AvroKey@10b85e	org.apache.avro.mapred.AvroValue@1
> org.apache.avro.mapred.AvroKey@877ec817	org.apache.avro.mapred.AvroValue@1
> org.apache.avro.mapred.AvroKey@3f904e5b	org.apache.avro.mapred.AvroValue@1
> org.apache.avro.mapred.AvroKey@b581cda5	org.apache.avro.mapred.AvroValue@1
> {code}
> I think all that needs to be done is implement toString() on AvroWrapper. It should return
its datum as JSON.
