Question

通过stormsubmitter.submittopoloy提交我的topo。可以在风暴用户界面中看到地形，但发出的数字始终为0。

    TopologyBuilder builder = new TopologyBuilder();
    builder.setSpout("WordSpout", new WordSpout());
    builder.setBolt("WordSplitBolt", new WordSplitBolt(),5).shuffleGrouping("WordSpout");
    builder.setBolt("WordCountBolt", new WordCountBolt(),5).fieldsGrouping("WordSplitBolt", new Fields("word"));
    builder.setBolt("WordReportBolt", new WordReportBolt(),10).globalGrouping("WordCountBolt");



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



    try{
        StormSubmitter.submitTopology("wordcount-topo", cfg, builder.createTopology());
    }
    catch (AlreadyAliveException e)
    {

    }
    catch (InvalidTopologyException e)
    {

    }
    catch (AuthorizationException e)
    {

    }

Answer 1

已修复，应该是Java版本的差异。

目标风暴集群的Java版本是11。我用于开发topo的开发环境Java版本是8，这导致了问题。

调整Java版本以使它们相同，从而解决问题

集群中未执行风暴拓扑
