Description

Currently, GenericDatumReader/GenericDatumWriter data members are private. Is it possible to make them protected so that we could extend those classes and create our own special DatumReader/Writer? The reason we want to do that is because we've created our own base SpecificRecordEx that implements SpecificRecord and added put/get for primitive types. We now want to extend the GenericDatumReader/GenericDatumWriter to use those primitive put/get functions to reduce box/unbox for better performance.
Thanks,

Xiaolu
