> * Adding or Deleting ZooKeeper servers should reconfigure ha.zookeeper.quorum
> in core-site.xml if NameNode HA is enabled, hbase.zookeeper.quorum if HBase
> is installed, and templeton.zookeeper.hosts if WebHcat is installed.
> * Right now we set above properties automatically in web-ui when we
> reconfigure the respective service for the first time after deleting or
> introducing new zookeeper server in the cluster.
> * We should explicitly do the reconfiguration while adding or deleting action
> is done on zookeeper server.
> * if we had to surface the properties on service configuration page, We
> should also display the message while adding or removing ZooKeeper server
> that this action will reconfigure above properties.
