> Hive uses the library from src/contrib/hive/serde to do serialization/deserialization.
> We want to do a refactoring of the library to:
> 1. Split Serializer and Deserializer interface
> 2. Split Serializer/Deserializer and ObjectInspector interface
> 3. Change hive/metaserver and hive/ql to use the new SerDe framework
