> Cannot change Zookeeper Server from Ambari to different node
> ------------------------------------------------------------
>
> Key: AMBARI-14491
> URL: https://issues.apache.org/jira/browse/AMBARI-14491
> Project: Ambari
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Jeffrey Barr
>
> 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.
> {code}ValueError when adding ZooKeeper Server to a new master node.
