Could you disable `spark.kryo.registrationRequired`? Some classes may not
be registered but they work well with Kryo's default serializer.

In addition, the real way to test if it's working is to force serialization:
In Java:
Create array of all your classes:
// for kyro serializer it wants to register all classes that need to be
serialized
Class[]
bq. try adding scala.collection.mutable.WrappedArray
But the hint said registering scala.collection.mutable.WrappedArray$ofRef.class
, right ?
