------------------------------------

             Summary: Java API needs Encoder / Decoder interfaces
                 Key: KAFKA-869
                 URL: https://issues.apache.org/jira/browse/KAFKA-869
             Project: Kafka
          Issue Type: Improvement
    Affects Versions: 0.8
            Reporter: Xavier Stevens
            Priority: Minor


The current 0.8 API requires that a serializer class implements a constructor that takes a single VerifiableProperties argument. The built-in scala serializers default this argument to null. But when implementing a custom encoder from Java you won't get any compilation errors. However, at runtime you'll get a NoSuchMethodException when the Kafka producer tries to instantiate the class.

If this is actually a dependency for the serialization classes it should be made more clear for Java API usage. I could see adding an abstract base class or perhaps an init(VerifiableProperties props) method.
