> 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}
