error during KafkaServerStartable startup Prepare to shutdown kafka server KafkaServerStartable

I tried to start kafka server, but I am getting this below error.

FATAL Fatal error during KafkaServerStartable startup. Prepare to shutdown (kafka.server.KafkaServerStartable)
java.lang.RuntimeException: A broker is already registered on the path /brokers/ids/0. This probably indicates that you either have configured a brokerid that is already in use, or else you have shutdown this broker and restarted it faster than the zookeeper timeout so it appears to be re-registering.

How can I solve this error?

Thank You

Hi@akhtar,

This error occurs because zookeeper is running already. So kill the process first and then try again and it will work.

$ ps aux | grep zookeeper
$ kill -9 <zookeeper.properties process>

Thank You
