问题
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
回答1:
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).
