Drew Farris updated MAHOUT-274:
-------------------------------
Attachment: mahout-avro-examples.tar.gz
Very rudimentary exploration of using avro to produce writables.
Uses the avro specific java class generation facility to produce a structured
document class which is wrapped in a generic writable container for
serialization.
* clases on o.a.m.avro are produces from schema in
src/main/schemata/o../a../m../avro/AvroDocument.avsc using
o.a.m.avro.util.AvroDocumentCompiler
* provides a generic avro Writable implementation in
o.a.m.avro.mapred.SpecificAvroWritable
* see the test in src/test/java o.a.m.avro.mapred.SpecificAvroWritableTest to
see how this can be used
'mvn clean install' will run the whole shebang.
> Use avro for serialization of structured documents.

> Explore the intersection between Writables and Avro to see how serialization
> can be improved within Mahout.
> An intermediate goal is the provide a structured document format that can be
> serialized using Avro as an Input/OutputFormat and Writable
