Hi, i'm a beginner to the storm. in order words, i'm a newbie.
I have tried to upgrade from Storm 1.2.2 to 2.0.0. and confirmed that kafka spout lag does not work. changed the value of ui.disable.spout.lag.monitoring to false, but it did not work.
So I checked the log of storm ui and got the following error message.
org.apache.storm.utils.ShellUtils$ExitCodeException: Error: Could not find or load main class .apache-storm-2.0.0.lib-tools.storm-kafka-monitor.audience-annotations-0.5.0.jar
at org.apache.storm.utils.ShellUtils.runCommand(ShellUtils.java:271) ~[storm-client-2.0.0.jar:2.0.0]
at org.apache.storm.utils.ShellUtils.run(ShellUtils.java:194) ~[storm-client-2.0.0.jar:2.0.0]...
In version 1.2.2, the storm-kafka-monitor works fine. However, version 2.0.0 throws an error.
