> Currently, the client needs to specify several parameters based on which an appropriate
connection is created with the server. In case of dynamic service discovery, when multiple
HS2 instances are running, it is much more usable for the server to add its config parameters
to ZK which the driver can use to configure the connection, instead of the jdbc/odbc user
adding those in connection string.
> However, at minimum, client will need to specify zookeeper ensemble and that she wants
the JDBC driver to use ZooKeeper:

> beeline> !connect jdbc:hive2://vgumashta.local:2181,vgumashta.local:2182,vgumashta.local:2183/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2
