Hong Tang commented on HADOOP-6685:
-----------------------------------

bq. Could you please explain the motivation for extending these file formats to 
support all of these serialization systems? 

Being able to support so many different serialization framework in itself is a 
good exercise to ensure that the API is carefully designed to be future proof.

> Change the generic serialization framework API to use serialization-specific 
> bytes instead of Map<String,String> for configuration

> 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).
