How to run WordCountTopology from storm-starter in Intellij

Question

I work with Storm for a while already, but want to get started with development. As suggested, I am using IntelliJ (up to now, I was using Eclipse and did only write topolog

I managed to run it on my virtualbox, storm version 1.2.2:

just download https://github.com/apache/storm/blob/master/storm-multilang/python/src/main/resources/resources/storm.py and put it into any folder you want, for example: /apache-storm-1.2.2/examples/storm-starter/multilang/resources/ , and then change the main function:

public static void main(String[] args) throws Exception {

    SplitSentence pythonSplit = new SplitSentence();
    Map env = new HashMap();
    env.put("PYTHONPATH", "/apache-storm-1.2.2/examples/storm-starter/multilang/resources/");
    pythonSplit.setEnv(env);

    TopologyBuilder builder = new TopologyBuilder();

    builder.setSpout("spout", new RandomSentenceSpout(), 5);

    builder.setBolt("split",pythonSplit, 8).shuffleGrouping("spout");
    builder.setBolt("count", new WordCount(), 12).fieldsGrouping("split", new Fields("word"));

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

    if (args != null && args.length > 0) {
      conf.setNumWorkers(3);

      StormSubmitter.submitTopologyWithProgressBar(args[0], conf, builder.createTopology());
    }
    else {
      conf.setMaxTaskParallelism(3);

      LocalCluster cluster = new LocalCluster();
      cluster.submitTopology("word-count", conf, builder.createTopology());

      Thread.sleep(600000);

      cluster.shutdown();
    }
  }
