Subject [jira] [Updated] (AVRO-1232) Output of Avro data using MapReduce with TextOutputFormat is not useful
Date Thu, 17 Jan 2013 21:44:13 GMT

     [ https://issues.apache.org/jira/browse/AVRO-1232?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Doug Cutting updated AVRO-1232:
-------------------------------

    Attachment: AVRO-1232.patch

Here's a patch that adds a toString() method to AvroWrapper.  Is this what you had in mind?

We should probably add a test case before this is committed.

> 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.
