> The {{WritableSerializer}}, {{ValueSerializer}}, {{AvroSerializer}}, {{WritableComparator}} and {{ValueComparator}} use plain {{Kryo}} instances to copy the objects. In cases where {{Kryo}} fails to copy the object, e.g. missing no-arg constructor, the serializer and comparator instances fail even though the objects are serializable.
> As a fallback strategy I propose to copy the objects by serializing and deserializing them.
