zookeeper is not connected

The error message "zookeeper is not connected" usually means that the client application is not able to establish a connection with the ZooKeeper server. This could be due to various reasons such as incorrect server address or port, network connectivity issues, or firewall restrictions.

To resolve this issue, you can try the following steps:

1. Verify the server address and port number in the client application configuration.

2. Check if the ZooKeeper server is running and reachable from the client machine.

3. Ensure that there are no firewall restrictions blocking the connection between the client and server.

4. Try restarting the ZooKeeper server and the client application.

5. If the issue persists, you may need to check the ZooKeeper logs for any errors or contact your system administrator for further assistance.
