ZooKeeper Command Line Interface (CLI)
- To perform ZooKeeper CLI operations, first start your ZooKeeper server and then, ZooKeeper client by “bin/zkCli.sh”.

- Next, create a new znode by running create /zk_test my_data.
What type of connection is made with ZooKeeper by client?
Clients connect to a single ZooKeeper server. The client maintains a TCP connection through which it sends requests, gets responses, gets watch events, and sends heart beats. If the TCP connection to the server breaks, the client will connect to a different server.
