Could not find leader nimbus from seed hosts [sandbox.hortonworks.com]

anand_616 — Sun, 06 Nov 2016 13:39:50 GMT

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.
