Troubleshooting Could not find nimbus from seed hosts¶
Regular nimbus error¶
During infrastructure and PunchPlatform Stack deployment, you can meet the following issue.
The system use a wrong naming resolution.
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
