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

问题描述

我们正在 LocalCluster 中执行 Storm 拓扑.Storm 拓扑运行良好并且能够连接 Storm UI (8090).但是 Storm UI 没有显示正在运行的拓扑信息.

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();

并提交如下:

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

推荐答案

LocalCluster 没有 UI 支持...因此您看到的 UI 属于不同的 Storm 集群.

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

更准确地说:LocalCluster 并不是真正的集群；它是一个本地 JVM 进程，它执行整个拓扑(模拟真正的 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 块).如果你想提交到一个真正的集群(并获得一个 UI，你需要使用 StormSubmitter).

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).
