> Currently, the generic serialization framework uses Map<String,String> for the serialization specific configuration. Since this data is really internal to the specific serialization, I think we should change it to be an opaque binary blob. This will simplify the interface for defining specific serializations for different contexts (MAPREDUCE-1462). It will also move us toward having serialized objects for Mappers, Reducers, etc (MAPREDUCE-1183).
