> HIVE-2599 introduced using custom object for the row key. But it forces key objects to extend HBaseCompositeKey, which is again extension of LazyStruct. If user provides proper Object and OI, we can replace internal key and keyOI with those. 
> Initial implementation is based on factory interface.
> {code}
> public interface HBaseKeyFactory {
>   void init(SerDeParameters parameters, Properties properties) throws SerDeException;
>   ObjectInspector createObjectInspector(TypeInfo type) throws SerDeException;
>   LazyObjectBase createObject(ObjectInspector inspector) throws SerDeException;
> }
> {code}
