【问题描述】：
我有一个问题，执行一个示例以将 Storm 与 kafka 连接起来。我让kafka成功运行。下一步是连接storm。
这是示例代码。
/**
* @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());
}
}
我收到一个我不明白的错误。谁能帮忙？ 我认为，这与 zkRoot 的值有关。我尝试了不同的路径（例如 zookeeper 安装或数据，但没有任何效果。
