Thanks Doug, that helps a lot. I glossed over the "Specification" doc thinking that was some form of internal protocol doc.
Now that I know that is the spec for the "Specific" schemas/api, I think I can continue to fumble along. And thanks for the pointers to the Ant tasks.

The schema is an Avro Schema, as documented in the spec. http://hadoop.apache.org/avro/docs/current/spec.html One uses SpecificCompiler to generate Java classes and interfaces from schemas a protocols. Once you've generated this code, you can look at it to see the Java API for your data. There are Ant tasks to facilitate code generation: ProtocolTask and SchemaTask. http://hadoop.apache.org/avro/docs/current/api/java/org/apache/avro/spec ific/package-summary.html The documentation's not great. We need a simple tutorial showing how this is done. You can look at the unit tests for examples. Doug
