Hi@akhtar,

It is a must to set up ZooKeeper for Kafka. ZooKeeper performs many tasks for Kafka, but in short, we can say that ZooKeeper manages the Kafka cluster state. 

• Download ZooKeeper from the below-given link.

https://zookeeper.apache.org/releases.html 

• Unzip the file. Inside the conf directory, rename the file zoo_sample.cfg as zoo.cfg. 

• The zoo.cfg file keeps configuration for ZooKeeper, i.e. on which port the ZooKeeper instance will listen, data directory, etc.

• The default listen port is 2181. You can change this port by changing the client port.

• The default data directory is /tmp/data. Change this, as you will not want ZooKeeper's data to be deleted after some random timeframe. 

• Go to the bin directory.

• Start ZooKeeper by executing the command ./zkServer.sh start.
