> We didn't forced GenericUDAFEvaluator to be Serializable. I don't know how 
> previous serialization mechanism solved this but, kryo complaints that it's 
> not Serializable and fails the query.
> The log below is the example, 
> {noformat}
> java.lang.RuntimeException: com.esotericsoftware.kryo.KryoException: Class 
> cannot be created (missing no-arg constructor):
