Apache Storm遠程拓撲提交

Question

我一直在使用IDE（Eclipse）測試遠程提交Storm Topologies。 我成功地將簡單的風暴拓撲上傳到遠程Storm羣集，但奇怪的是，當我檢查Storm UI以確定遠程提交的拓撲是否正常工作時，我看到只是在用戶界面中_acker螺栓，但其他螺栓和噴口不在那裏。之後，我從命令行手動提交了拓撲，並再次檢查了Storm UI，並且它工作正常，沒有問題。我一直在尋找原因，但找不到。我連接兩個拓撲結構和下面遠程提交類和對應風暴UI畫面：

這是Eclipse控制檯輸出（遠程提交後）

這裏是拓撲：

//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

這裏是RemoteSubmitter類：

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(); 
    } 
} 
} 

這裏是風暴UI PICT（在遠程提交的情況下）

這裏是其他風暴UI PICT（在手動提交的情況下）

Answer 1

在RemoteSubmissionTopo中，您使用TopologyBuilder topoBuilder = new TopologyBuilder();，但不要撥打setSpout(...)/setBolt(...)。因此，您正在提交一個沒有運營商的拓撲...

Btw：RemoteSubmissionTopo實際上並不需要。您可以使用StormBenchmark遠程提交。只需在main中添加conf.put(Config.NIMBUS_HOST, "117.16.142.49");並設置JVM選項-Dstorm.jar=/path/to/topology.jar，即可運行。
