如何本地调试Storm topology

来源：互联网发布：医保报销软件编辑：程序博客网时间：2024/05/21 17:35

1. 在Main程序中，要使用 LocalCluster提交topology

LocalCluster cluster = new LocalCluster();cluster.submitTopology("word-count", conf,        builder.createTopology());Thread.sleep(10000);cluster.shutdown();

2. 如果是Maven工程，则最好单独制作Storm工程，使pom.xml中只有storm程序需要的依赖和repository，

否则可能会导致某些类或方法找不到，引起 Error on initialization of server mk-worker

pom.xml
