Aaron Kimball commented on HADOOP-6438:
---------------------------------------
> A package feels like overkill to me. Do we expect more than a single class?
Depends? There are currently two ways to set the metadata: In most cases,
setting the serialized class name is sufficient. (e.g., JavaSerialization,
WritableSerialization, AvroSpecificSerialization). In the
AvroGenericSerialization case, though, we set the schema to serialize, using an
analogous but distinct API. We could maybe add a single class that contains
methods like {{setMapOutputKeyClass()}} and {{setMapOutputKeySchema()}}; the
current implementation breaks these apart, making the serialization system
being used more explicit in the class name to which the configuration method
belongs. I could go either way on this issue.
> Add configuration getters/setters to serialization classes
