> Key: AVRO-1232
> URL: https://issues.apache.org/jira/browse/AVRO-1232
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.7.3
> Reporter: Garrett Wu
> Priority: Minor
>
> 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.
