Re: NoSuchMethodError with Consumer Instantiation

[Jaikiran Pai]

You probably have the wrong version of the Kafka jar(s) within your 
classpath. Which version of Kafka are you using and how have you setup 
the classpath?

Hi,
I am trying to set up Kafka in our cluster and I am running into the

I am guessing that it is missing certain classpath references. If that is
the reason, could someone tell me which jar is it?

If not, what is it that I am missing?


*KafkaConsumer:*


public KafkaConsumer(String topic)

{

* consumer = Consumer.createJavaConsumerConnector(createConsumerConfig());
//line where the error is thrown*

  this.topic = topic;

}

  private static ConsumerConfig createConsumerConfig()

{

  Properties props = new Properties();

     props.put("zookeeper.connect", "IP:PORT");

     props.put("group.id", "group1");

     props.put("zookeeper.session.timeout.ms", "6000");

     props.put("zookeeper.sync.time.ms", "2000");

     props.put("auto.commit.interval.ms", "60000");


     return new ConsumerConfig(props);

  }


TIA!
