当我使用shell风暴的Cpp包装器(StormCpp)使用ShellBolt的multilang子进程时,我遇到了一个风暴错误,这个给了我下一个错误:
10784 [Thread-17-split] ERROR backtype.storm.util - 异步循环死了! java.lang.RuntimeException:启动multilang子进程时出错
这是我的拓扑Java代码:
public class AppCppStorm {
public static class CppStorm extends ShellBolt implements IRichBolt {
public CppStorm()
{
super("test");
}
@Override
public void declareOutputFields(OutputFieldsDeclarer declarer) {}
@Override
public Map<String, Object> getComponentConfiguration() {
return null;
}
}
public static void main(String[] args) throws Exception {
TopologyBuilder builder = new TopologyBuilder();
builder.setSpout("spout", new RandomSentenceSpout());
builder.setBolt("split", new CppStorm())
.shuffleGrouping("spout");
Config conf = new Config();
conf.setDebug(true);
conf.setNumWorkers(3);
conf.setMaxTaskParallelism(3);
LocalCluster cluster = new LocalCluster();
cluster.submitTopology("test", conf, builder.createTopology());
Thread.sleep(10000);
cluster.shutdown();
}
}
如果有人能在这一点上帮助我,我会很感激。

我发现了这个错误,我没有加入我的ShellBolt&amp; Incanciation,这是我Bolt Cpp应用程序的绝对路径。
