风暴UI拓扑不起作用 [英] Storm UI topology not working

问题描述

我们在 LocalCluster 中执行Storm拓扑。
风暴拓扑运行良好并且能够连接Storm UI（8090）。
但Storm UI未显示正在运行的拓扑信息。

  LocalCluster cluster = new LocalCluster（）; 
  

并提交如下：

  bin / storm jar bin / StormTest-0.0.1-SNAPSHOT.jar com.abzooba.storm.twitter.TwitterTopologyCreator Twitter 
  

解决方案

LocalCluster 没有UI支持...因此您看到的用户界面属于到另一个Storm集群。更准确地说： LocalCluster 不是一个真正的集群;它是执行整个拓扑的本地JVM进程（模仿真正的Storm集群）。因此， bin / storm jar ... 不会将拓扑发送到任何集群，而是运行本地JVM（我假设 bin / storm blocks）。如果你想提交一个真正的集群（并获得一个UI，你需要使用 StormSubmitter ）。

We are executing a Storm topology in LocalCluster. Storm topology is executing fine and able to connect Storm UI (8090). But Storm UI is not displaying the running topology information.

LocalCluster cluster = new LocalCluster();

and submitting like:

bin/storm jar bin/StormTest-0.0.1-SNAPSHOT.jar com.abzooba.storm.twitter.TwitterTopologyCreator Twitter

解决方案

LocalCluster does not have UI support... Thus the UI you are seeing belongs to a different Storm cluster.

To be more precise: LocalCluster is not really a cluster; it's a local JVM process that executes the whole topology (mimicking a real Storm cluster). Thus, bin/storm jar ... does not send the topology to any cluster but runs a local JVM (I assume, that bin/storm blocks). If you want to submit to a real cluster (and get an UI, you need to use StormSubmitter).
