Answer 1

You are trying to start a kafka server but you are passing the wrong config file.

Usually you want to start a kafka server using the following command:

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

And is in this file where you specify the address of the zookeeper:

zookeeper.connect=kafka01:2181,kafka02:2181,kafka03:2181

The quickstart guide in the kafka official documentation is quite good, I recommend you to have a look at it. You can find it here.

Answer 2

You stared the wrong script. It should be:
bin/zookeeper-server-start.sh config/zookeeper.properties

Answer 3

You are trying to start kafka server with zookeeper config properties file and that's why you are getting the above error.

Use the commands below instead:

Zookeeper:

.\bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

Kafka:

.\bin\windows\kafka-server-start.bat .\config\server.properties
