How to use JsonEncoder for output serialization of AvroMapReduce?

Hi,

I am newbie.

Is there a way to make the output of AvroMapReduce to use JsonEncoder instead of BinaryEncoder?



(On org.apache.avro.mapred.AvroSerialization, it seems that the BinaryEncoder is hardcoded in the file)

Thanks,

David Shimon

The data file format is currently defined to always use the binary
encoding.  The json encoding is optional.

For json, a text file with one record per line is a common format,
perhaps where the first line in the file is the schema.
