Description

When you are managing Avro Schemas in your source code and you have the Java classes to serialize/deserialize Avro, it would be easier to do something like:

store a into 'tmp/myuser' using AvroStorage(null, '-schemaclass com.myco.MyUser')

Rather than passing as the first agurment, the entire Avro schema json in the pig script, or keeping a (potentially outdated) set of Avro schema files in HDFS for the -schemafile option.

If your classpath is already aware of how to serialize/deserialize the Avro data, it would be good to leverage that with a fully qualified classname.
