Description

While adding a master node, any attempts to change the zookeeper server from Ambari are not allowed as the params.zookeeper_hosts value is not updated or changed whether I attempt to move the zookeeper hosts to the master or a different data node. All attempts at installing the zookeeper server fail.

ValueError when adding ZooKeeper Server to a new master node.
