public class KafkaSerDe
extends AbstractSerDe

Generic Kafka Serde that allow user to delegate Serde to other class like Avro, Json or any class that supports BytesWritable. I the user which to implement their own serde all they need is to implement a serde that extend AbstractSerDe and accept BytesWritable as value
