Kafka service start fail - apache-kafka

Question

I'm trying to install kafka on my Ubuntu 16.04 machine.
I followed instruction of below link
https://www.digitalocean.com/community/tutorials/how-to-install-apache-kafka-on-ubuntu-18-04
As I end up create /etc/systemd/system/kafka.service
and try to start service with 'sudo systemctl start kafka'
It doesn't print any message, I could know that starting service is failed by checking output of
sudo journalctl -u
It says
sudo journalctl -u kafka
<pre><code>
kafka.service: Main process exited, code=exited, status=1/FAIL
kafka.service: Control process exited, code=exited status=1
kafka.service: Unit entered failed state.
kafka.service: Failed with result 'exit-code'.
</code></pre>
cat kafka.log

Thank you in advance!!!

Answer 1

Your zookeeper server may be gone to idle state. You can just to go to the terminal of zookeeper and hit enter. After that you can try again.
