I have an issue, executing a sample to connect storm with kafka. I got kafka running successfully. The next step would be to connect storm.
This is the sample code.
/**
* @author Amit Kumar
*/
public class Topology {
private static final Logger LOG = Logger.getLogger(Topology.class);
public static void main(String[] args) {
// Build Spout configuration using input command line parameters
final BrokerHosts zkrHosts = new ZkHosts("gitserver:2181");
final String kafkaTopic = "test";
final String zkRoot = "";
final String clientId = "client1";
final SpoutConfig kafkaConf = new SpoutConfig(zkrHosts, kafkaTopic, zkRoot, clientId);
kafkaConf.scheme = new SchemeAsMultiScheme(new StringScheme());
// Build topology to consume message from kafka and print them on console
final TopologyBuilder topologyBuilder = new TopologyBuilder();
// Create KafkaSpout instance using Kafka configuration and add it to topology
topologyBuilder.setSpout("kafka-spout", new KafkaSpout(kafkaConf), 1);
//Route the output of Kafka Spout to Logger bolt to log messages consumed from Kafka
topologyBuilder.setBolt("print-messages", new LoggerBolt()).globalGrouping("kafka-spout");
// Submit topology to local cluster i.e. embedded storm instance in eclipse
final LocalCluster localCluster = new LocalCluster();
localCluster.submitTopology("kafka-topology", new HashMap(), topologyBuilder.createTopology());
}
}
I get an error that I don't understand. Who can help? I think, it has to do with the value of zkRoot. I tried different paths (e.g. the zookeeper installation or data, but nothing works.

Please use storm-kafka-client instead of storm-kafka for new code, the latter is deprecated.
The error you're seeing is likely due to mixing different Kafka versions in your classpath. I looked up the class you're getting the error from, and the constructor the error mentions is present in Kafka 0.9 (https://github.com/apache/kafka/blob/0.9.0.0/clients/src/main/java/org/apache/kafka/common/network/NetworkSend.java#L26) but not 0.8 (https://github.com/apache/kafka/blob/0.8.2.2/clients/src/main/java/org/apache/kafka/common/network/NetworkSend.java#L26)
Most likely you're accidentally mixing in Kafka 0.8 classes into your build. I'd use mvn dependency:tree to check your topology, and make sure all Kafka jars are from the same version.
