I'd appreciate any help in resolving the exception I'm getting while trying to run my first Storm topology based on a very simple Word Count example I found on internet. I'm running following command:
storm jar StormWordCounter-0.0.1-SNAPSHOT.jar demo.storm.WordStormProd MySampleFile.txt
Please see my attached code wordstormprod.txt
The detailed exception as following:
11033 [main] WARN o.a.s.u.NimbusClient - Ignoring exception while trying to get leader nimbus info from sandbox.hortonworks.com. will retry with a different seed host.
