Hello,
I'm new to Apache Storm, and have run into some trouble running the
storm-starter ExclamationTopology example. I'm running on a MacBookPro with
Mojave, I've downloaded and installed the Storm binary tar, and generated
the storm-starter uber-jar with no (obvious) errors. When I run locally
with the following command:
storm jar storm-starter-1.2.2.jar
org.apache.storm.starter.ExclamationTopology
I get alot of output; bracketing the Local processing in main...
*else* {
LocalCluster cluster = *new* LocalCluster();
System.*out*.println("Starting Topology......");
cluster.submitTopology("test", conf, builder.createTopology());
System.*out*.println("Ending Topology......");
Utils.*sleep*(10000);
cluster.killTopology("test");
cluster.shutdown();
}
isolates the following info/error:

I've searched, and it looks like information about the processing should
appear here instead. I haven't found anything specific to Storm concerning
this error. I have found references to it for Zookeeper, so tried
installing and running Zookeeper and Kafka, with no improvement; the Storm
tutorial didn't state this was required, but I thought I'd try anyway. At
this point, I've exhausted my guesses, and was hoping someone could help
point me in the proper direction. I appreciate any suggestions...
