------------------------------------
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.
