Hi, I noticed on the page about serialization ( https://github.com/nathanmarz/storm/wiki/Serialization) that storm only registers HashMap and HashSet for serialization with Kryo. The reason I noticed is I noticed that in some cases when I have a class that contains a member of type Map, storm defaults to Java serialization. When I changed the class member type to HashMap, it uses Kryo. However, I'd prefer to keep it as Map so that the member field is not as specific. In order to keep this as a Map (and use Kryo instead of java serialization), do I need to register a custom serializer for the Map interface?
Thanks, Nathan
