Hi, I think maybe it's better to have an option to force class registration when using Kryo, mainly to prevent human errors. Kryo has a setRegistrationRequired method and by default the check is false (in kryo and in chill). Maybe we can have a system property for setting this? Like:
System.setProperty("spark.kryo.registrationRequired", true)
What you say about this?
