ZK 3.5, which is currently in ALPHA state, will have dynamic cluster membership. This will mean that you can add/remove servers and everything that is connected will adjust automatically. All clients (like Solr) and servers will need to be updated to the new version. Currently Solr uses ZK 3.4.6. Even after Solr is updated to a 3.5 version of ZK and the code gets any changes that might be required, the list of servers that Solr and SolrJ clients *start* with might still need manual adjustment. After the upgrade to 3.5, if at least one of the servers in the start list is correct, the rest might be discovered, but it's better to keep that list current. Thanks, Shawn
