Hi Pavel- The ZooKeeper CLI does not have a way to get information about the cluster. Although, there are other ways to get that information. You can use four letter words (https://zookeeper.apache.org/doc/r3.4.10/zookeeperAdmin.html#sc_zkCommands) or JMX (https://zookeeper.apache.org/doc/r3.4.10/zookeeperJMX.html).
If you are running a version >= 3.5.0 you can use the AdminServer (https://zookeeper.apache.org/doc/r3.5.3-beta/zookeeperAdmin.html#sc_adminserver), which provides the same functionality as four letter words. Regarding your second question, it is ok to not include all of the nodes on the cluster. Just be aware that a client will only be aware of the nodes provided in the connection string and will not be able to connect if all of the nodes provided are unavailable. Hope this helps.
