如何在示例化apache storm localcluster时指定zookeer信息

我想示例化一个localcluster（），防止它运行自己的嵌入式zookeeper，而使用我的。
关于这个问题：“https://issues.apache.org/jira/browse/storm-213“已为版本0.9.3解析。
能给我一个示例代码吗？
ps：我正在集成测试我的storm拓扑，我使用kafka和zookeeper作为storm的输入。当我没有将zookeeper信息指定给localcluster时，我在“localcluster localcluster=new localcluster（）”行得到这个异常：

当我为本地集群指定“storm.zookeeper.servers”和“storm.zookeeper.port”时，我在“localcluster.submittopology（）”行得到以下异常：

你可以使用过载 LocalCluster 建造师。

LocalCluster cluster = new LocalCluster("localhost", 2181L);

我能够使用kafka作为storm拓扑的输入，通过使用这个链接提供的配置http://storm.apache.org/releases/1.0.2/storm-kafka.html
我为storm配置创建了一个特定的java类

public class StormConfig {

private String zooKeeperConnect;

public StormConfig() {

}
public KafkaSpout getkafkaSpout(String topic){
    return new KafkaSpout(this.getSpoutConfig(topic));
}

public SpoutConfig getSpoutConfig(String topic) {
    SpoutConfig spoutConfig=new SpoutConfig(this.getZkHosts(), topic, "", topic);
    spoutConfig.scheme = new SchemeAsMultiScheme(new StringScheme());
    spoutConfig.startOffsetTime=kafka.api.OffsetRequest.EarliestTime();
    return spoutConfig;
}

public ZkHosts getZkHosts() {
    return new ZkHosts(getZooKeeperConnect());
}

public String getZooKeeperConnect() {
    return zooKeeperConnect;
}

public void setZooKeeperConnect(String zooKeeperConnect) {
    this.zooKeeperConnect = zooKeeperConnect;
}
}

然后我在创建拓扑的初始喷口时使用了此类中的方法：

builder.setSpout("kafkaSpoutName", stormConfig.getkafkaSpout("topicName"))
            .setNumTasks(Constants.SPOUT_NUM_TASKS);
