Hello, With 'DynamicReconfig' feature in v3.5.7, ideally the servers can be added and removed without restarting ZooKeeper service on any of the nodes.
But, with Keberos based quorum authentication/authorization enabled via '_HOST' principal check, this is not possible. Because, when you try to add a new server, it won't be able to connect to any of the members in the node and won't be synced. As all the members reject it based on authorization. For it to work, you need to do 'reconfig', then restart leader, the new member and rest of the members. Is this the expected behavior with DynamicReconfig? Or am I missing something here. -- Sent from: http://zookeeper-user.578899.n2.nabble.com/
