You do not need additional zookeeper hosts to run more Solr hosts. Three hosts are all that is required for a fully redundant ZK ensemble, no matter how many Solr hosts are in your cloud. I'm not sure what you're gaining by restarting the existing Solr hosts, either. If you want to add more Solr hosts, just start them up with the correct parameter (-DzkHost, etc) so they register themselves with zookeeper. They will immediately be available for replica migrations or anything else you might want to do. Thanks, Shawn
