Review Comment:
Thank you for adding the test !
> I wonder if this is a expected behavior given that we use a different
serializer or there is something wrong in the way I build the test.
A bit strange though, have mostly seen other way round, things that are
serializable by Java serializer are not kryo serializable, I also tried it
locally and AssumeRoleRequest is indeed kryo serializable.
Can you plz add the complete stacktrace you see in Spark Serialization
failure with java serializer
