2. Switch to the Kafka client installation directory, for example, /opt/client.

   cd /opt/client

3. Run the following command to switch to the Kafka client configuration directory:

   cd Kafka/kafka/config

4. Open the tools-log4j.properties file, change WARN to INFO, and save the file.

   

   

5. Switch to the Kafka client installation directory, for example, /opt/client.

   cd /opt/client
