我正在尝试在集群中执行拓扑。我编写了一个拓扑并将其编译成jar，然后将其注册到集群。但由于某些原因，拓扑结构似乎没有运行。我只想用这里的风暴作为管道。使用cmd注册： ./storm jar /tmp/storm_test.jar storm.topology.MyTopology /tmp/bigFile.log 拓扑结构：

package storm.topology;

import storm.spouts.LineReaderSpout;

import backtype.storm.Config;
import backtype.storm.StormSubmitter;
import backtype.storm.topology.TopologyBuilder;
import storm.bolts.Bolt;

public class MyTopology {
    public static long tupleCounter = 0;
    public static long endTime = 0;

    public static void main(String[] args) throws Exception {
        Config config = new Config();
        config.put("inputFile", args[0]);
        config.put(Config.TOPOLOGY_WORKERS, 4);
        config.setDebug(true);
        config.put(Config.TOPOLOGY_MAX_SPOUT_PENDING, 10);

        TopologyBuilder builder = new TopologyBuilder();
        builder.setSpout("line-reader-spout", new LineReaderSpout());

        builder.setBolt("boltA", new Bolt()).shuffleGrouping("line-reader-spout");

        StormSubmitter.submitTopology("mytopology", config, builder.createTopology()); 
    }
}
