Troubleshooting Could not find nimbus from seed hosts

Regular nimbus error

During infrastructure and PunchPlatform Stack deployment, you can meet the following issue.

Reason

The system use a wrong naming resolution.

Solution

1) For the first deployment - Check the availability of the naming resolution server. - Check the /etc/hosts. The local production IP must be resolved the full fqdn (System norm). - Check the network access to the zookeeper servers (get the server names and tcp port in the punchplatform.properties)

2) For other deployment or after migration ONLY :

Storm stores data in zookeeper including. If you decide to redeploy storm nimbus, you may have to clean zookeeper by executing :

punchplatform-zookeeper-console.sh
> rmr /<root_prefix/storm-<name_cluster>

WARNING : - Make sure there is no topology running on this cluster especially if you're un production platform !!! - Check twice the first solution
