You need to start the zookeeper with:

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

Then you need to start the kafka-server using:

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

Now your kafka will run smoothly

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

This is the error because there is an issue with your command.

To start zookeeper run -

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

To start server run -

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

There are two ways you can start Kafka server:

  1. Start the zookeeper server separately(on your local or another machine)
  2. Start the zookeeper server which is embedded with Kafka server (kafka_2.12/libs/zookeeper-3.4.13.jar)

In first case: I am assuming you have started the zookeeper server already and that is running on localhost:2181

So now you are good to start kafka server using following command

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

In server.properties file you have to tell Kafka server where is/are the zookeeper(s) running. Using property:

## zookeeper.connect=localhost:2181 [default]
zookeeper.connect=zk1:2181, zk2:2181, localhost:2181

In second case

Start the zookeeper first (embedded with the Kafka server)

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

Then, start the Kafka server:

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

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

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.
