Hi Abhijith, You should be using KafkaProducer, but KafkaConsumer is not ready yet. The APIs are included in 0.8.2.1, but the implementation is not ready. Until 0.8.3 is released, you cannot rely only on kafka-clients if you want to write a consumer. You'll need to depend on the main kafka jar and use kafka.consumer.Consumer, as described on that wiki page. It has not been deprecated yet since the new consumer implementation is not ready yet.
