我一直在使用ide(eclipse)测试storm拓扑的远程提交。我成功地将简单的storm拓扑上传到远程storm集群,但奇怪的是,当我检查storm ui以确定远程提交的拓扑是否正常工作时,我在ui中只看到了\u acker bolt,但其他bolt和spout不在那里。之后,我从命令行手动提交了拓扑,并再次检查了StormUI,它可以正常工作,没有任何问题。我一直在找原因,但找不到。我在下面附上了拓扑和远程提交者类以及相应的storm ui图片:
这是eclipse控制台的输出(在远程提交之后)

以下是拓扑:

public class StormBenchmark {

//******************************************************************************************
public static class GenSpout extends BaseRichSpout {

    //private static final Logger logger = Logger.getLogger(StormBenchmark.class.getName());

    private Long count = 1L;
    private Object msgID;
    private static final long serialVersionUID = 1L;
    private static final Character[] CHARS = new Character[] { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'};
    private static final String[] newsagencies = {"bbc", "cnn", "reuters", "aljazeera", "nytimes", "nbc news", "fox news", "interfax"}; 

    SpoutOutputCollector _collector;
    int _size;
    Random _rand;
    String _id;
    String _val;
    // Constructor
    public GenSpout(int size) {
        _size = size;
    }  

    public void open(Map conf, TopologyContext context, SpoutOutputCollector collector) {
        _collector = collector;
        _rand = new Random();
        _id = randString(5);
        _val = randString2(_size);
    }
    //Business logic
    public void nextTuple() {

        count++;
        msgID = count;
        _collector.emit(new Values(_id, _val), msgID);
    }

    public void ack(Object msgID) {
        this.msgID = msgID;
    }

    private String randString(int size) {

        StringBuffer buf = new StringBuffer();
        for(int i=0; i<size; i++) {
            buf.append(CHARS[_rand.nextInt(CHARS.length)]);
        }
        return buf.toString();
    }

    private String randString2(int size) {

        StringBuffer buf = new StringBuffer();
        for(int i=0; i<size; i++) {
            buf.append(newsagencies[_rand.nextInt(newsagencies.length)]);
        }
        return buf.toString();
    }

    public void declareOutputFields(OutputFieldsDeclarer declarer) {
        declarer.declare(new Fields("id", "item"));
    }        
}
// =======================================================================================================
// =================================== B O L T ===========================================================
public static class IdentityBolt extends BaseBasicBolt {    

    private static final long serialVersionUID = 1L;

    public void declareOutputFields(OutputFieldsDeclarer declarer) {
        declarer.declare(new Fields("id", "item"));
    }
    public void execute(Tuple tuple, BasicOutputCollector collector) {

        String character = tuple.getString(0);
        String agency = tuple.getString(1);
        List<String> box = new ArrayList<String>();
        box.add(character);
        box.add(agency);
        try {
            fileWriter(box);
        } catch (IOException e) {
            e.printStackTrace();
        }
        box.clear();
    } 

    public void fileWriter(List<String> listjon) throws IOException {

        String pathname = "/home/hduser/logOfStormTops/logs.txt";
        File file = new File(pathname);
        if (!file.exists()){
            file.createNewFile();
        }
        BufferedWriter writer = new BufferedWriter(new FileWriter(file, true));

        writer.write(listjon.get(0) + " : " + listjon.get(1));
        writer.newLine();
        writer.flush();
        writer.close();         
    }
}

//storm jar storm-benchmark-0.0.1-SNAPSHOT-standalone.jar storm.benchmark.ThroughputTest demo 100 8 8 8 10000
public static void main(String[] args) throws Exception {

    TopologyBuilder builder = new TopologyBuilder();

    builder.setSpout("spout", new GenSpout(8), 2).setNumTasks(4);

    builder.setBolt("bolt", new IdentityBolt(), 4).setNumTasks(8)
            .shuffleGrouping("spout");

    Config conf = new Config();
    conf.setMaxSpoutPending(200);
    conf.setStatsSampleRate(0.0001);
    //topology.executor.receive.buffer.size: 8192 #batched
    //topology.executor.send.buffer.size: 8192 #individual messages
    //topology.transfer.buffer.size: 1024 # batched

    conf.put("topology.executor.send.buffer.size", 1024);
    conf.put("topology.transfer.buffer.size", 8);
    conf.put("topology.receiver.buffer.size", 8);
    conf.put(Config.TOPOLOGY_WORKER_CHILDOPTS, "-Xdebug -Xrunjdwp:transport=dt_socket,address=1%ID%,server=y,suspend=n");

    StormSubmitter.submitTopology("SampleTop", conf,   builder.createTopology());
}
}

下面是remotesubmitter类:

public class RemoteSubmissionTopo {

@SuppressWarnings({ "unchecked", "rawtypes", "unused" })
public static void main(String... args) {

    Config conf = new Config();
    TopologyBuilder topoBuilder = new TopologyBuilder();
    conf.put(Config.NIMBUS_HOST, "117.16.142.49");
    conf.setDebug(true);
    Map stormConf = Utils.readStormConfig();
    stormConf.put("nimbus.host", "117.16.142.49");
    String jar_path = "T:\\STORM_TOPOLOGIES\\Benchmark.jar";

    Client client = NimbusClient.getConfiguredClient(stormConf).getClient();

    try {
        NimbusClient nimbus = new NimbusClient(stormConf, "117.16.142.49", 6627);
        String uploadedJarLocation = StormSubmitter.submitJar(stormConf, jar_path);
        String jsonConf = JSONValue.toJSONString(stormConf);

        nimbus.getClient().submitTopology("benchmark-tp", uploadedJarLocation, jsonConf, topoBuilder.createTopology());

    } catch (TTransportException e) {
        e.printStackTrace();
    } catch (AlreadyAliveException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InvalidTopologyException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (TException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        Thread.sleep(6000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

这是storm ui图片(在远程提交的情况下)

这是另一个storm ui图片(在手动提交的情况下)

RemoteSubmissionTopo 你用 TopologyBuilder topoBuilder = new TopologyBuilder(); 但不要打电话 setSpout(...) / setBolt(...) . 因此,您提交的拓扑没有运算符。。。
顺便说一句: RemoteSubmissionTopo 实际上根本不需要。你可以用 StormBenchmark 远程提交。只需添加 conf.put(Config.NIMBUS_HOST, "117.16.142.49");main 并设置jvm选项 -Dstorm.jar=/path/to/topology.jar 你很适合跑步。
