Every time I stop the kafka server and start it again it doesn't start properly and I have to restart my whole machine and start the kafka server. Does anybody know how I can restart kafka server without having to restart my machine? Actually I would like to terminate the consumer from last session.

Thank you,

Zeinab

If your Kafka broker is running as a service (found under /lib/systemd/system/) from a recent Confluent Platform release, you can stop it using:

systemctl stop confluent-kafka.service

or if you'd like to restart the service,

systemctl restart confluent-kafka.service

Otherwise, you can stop your broker using

./bin/kafka-server-stop.sh

and re-start it:

./bin/kafka-server-start.sh config/server.properties

If you want to stop a specific consumer, simply find the corresponding process id: 

ps -ef | grep consumer_name

and kill that process:

kill -9 process_id
