@rdblue > I think this can be collapsed into a single DynConstructors call that lists both implementations. The issue with that approach is that I still need a boolean to check if I need to call the `setConf` for no-arg constructor, and there was no way to get that boolean. I guess I can bypass that by checking `instanceof Configurable` for all FileIOs, so if we decide to go with that route I can make the change accordingly. > can you elaborate on your performance concerns if the configuration isn't final? I would actually prefer to use this approach of adding no-arg consturctor for `HadoopFileIO` which makes the whole concept of FIleIO loading much simpler. But I see `conf()` is called in all read and write paths to create a serializable configuration to avoid Kryo serialization issue. There is definitely a small difference for using final versus not final, but the difference might not be significant from a broader view, I do not have a definitive answer for that. -- This is an automated message from the Apache Git Service.
