我有一个问题，执行一个示例来连接storm和Kafka。我成功地运行了kafka。下一步将是连接storm。
这是示例代码。

/**

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());
    }
}

我遇到了一个我不理解的错误。谁能帮我？我想，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。
