Arun C Murthy commented on HADOOP-6685:
---------------------------------------
bq. I agree. So let's create new formats outside of Hadoop's kernel, rather
than add new ones in.
Great. No one is suggesting new formats. We need to maintain the ones we
already have for legacy reasons.
There is petabytes of data in SequenceFile format in Hadoop clusters
everywhere. We cannot drop it, we need to maintain it and keep it up to date.
We also need to improve to continue to support existing users.
> 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).
