在本地提交拓扑时出现Apache风暴错误

Question

我试图在本地提交我的Storm拓扑。但是，在调用cluster.submitTopology()时，我一直在控制台上收到此错误：

  

[Thread-5] ERROR backtype.storm.event - 处理事件时出错   java.lang.IllegalStateException：试图调用未绑定的fn：   ＆＃39;？backtype.storm.util /一些

     

[Thread-5] ERROR backtype.storm.util - 停止过程：（＆＃34;错误时   处理事件＆＃34;）

public static void main(String[] args) throws Exception {

    TopologyBuilder builder = new TopologyBuilder();

    builder.setSpout("twitterspout", new TwitterSpout());
    builder.setBolt("sentiment", new SentimentBolt()).shuffleGrouping("twitterspout");
    builder.setBolt("dimension", new DimensionBolt()).shuffleGrouping("twitterspout");
    builder.setBolt("clustering", new ClusteringBolt())
    .fieldsGrouping("dimension", new Fields("dimension"))
    .fieldsGrouping("sentiment", new Fields("sentiment"));

    Config conf = new Config();
    conf.setDebug(true);


    System.out.print("Creating local Cluster...");
    LocalCluster cluster = new LocalCluster();
    System.out.println("Done!");

    cluster.submitTopology("enrichment", conf, builder.createTopology());

}

感谢任何帮助。
