Until a stable Zookeeper release supports SSL/TLS, Kafka brokers could implement a strategy called Encrypt-then-MAC to encrypt sensitive metadata information about delegation tokens and protecting integrity using the master secret key (i.e. Delegation.token.master.key) as a shared secret.
To install Apache Kafka on Mac, Java is the only prerequisite. First we shall look into the installation steps of Java and then we shall setup Apache Kafka and run it on the Mac.
Install Java
- Open a browser and hit the url [http://www.oracle.com/technetwork/java/javase/downloads/index.html].
- Click on JDK, check “Accept License Agreement” and download .dmg file for installation on Mac.
- Double click on the downloaded file and proceed with the installation steps.
- You have successfully installed Java. You may delete the .dmg file, as memory is costly on Mac.
You may verify the installation of Java on Mac, by running the following command on a Terminal.
java -version |
Install Apache Kafka on Mac
- Download the latest Apache Kafka from [https://kafka.apache.org/downloads] under Binary downloads.
- Click on any of the binary downloads, or choose a specific scala version if you have any dependency with scala in your development.
- Go with the recommended mirror site.
- Extract the contents. Navigate to root of Apache Kafka folder and open a Terminal. Or Open a Terminal and navigate to the root directory of Apache Kafka. apples-MacBook-Pro:kafka_2.12-1.0.0Prasanth$ ls
Start Zookeeper
Kafka Tool For Mac Os
Apache Kafka depends on Zookeeper for cluster management. Hence, prior to starting Kafka, Zookeeper has to be started. There is no need to explicitly install Zookeeper, as it comes included with Apache Kafka.
Kafka Tool For Mac Windows
From the root of Apache Kafka, run the following command to start Zookeeper :
~$sh bin/zookeeper-server-start.sh config/zookeeper.properties |
Yemuzip 2 5 – easy to use zip compression utility. The zookeeper should be started with a similar following trace in the output.

Start Apache Kafka Server
Open another Terminal and run the following command from the root of Apache Kafka to start Apache Kafka.
~$sh bin/kafka-server-start.sh config/server.properties |
Following should be the end of trace stating that Kafka server is started.

Conclusion :
In this Apache Kafka Tutorial, we have successfully learnt to install Apache Kafka on Mac and start Kafka along with Zookeeper.
- You're looking for an awesome tool to get insights into your @apachekafka cluster, manage brokers & topics, etc?— René Kerner (@rk3rn3r) July 28, 2019
Have a look at @getconduktor. It's awesome and it's free during beta.
??? https://t.co/hbr04bMfJE - Anyone working with #kafka should give @getconduktor a spin. If you are worried about #support, this example of 33 minutes from error to solution should help calm your fears :) https://t.co/Vncg55lx7epic.twitter.com/wnusJrO3ov— Mitchell Turner (@mitchelldturner) February 10, 2020
- It’s quite fascinating how @getconduktor empowers a humble business user like myself to deep dive into Kafka. Should be on every Product Manager desktop. #kafka— Cedric Sadai (@yeahscience) December 17, 2019
- If you work with kafka, check out @getconduktor . Really slick GUI and they have been adding features at a super rapid pace. My favorite feature is jq DSL projections of JSON messages.— Peter Lyons (@focusaurus) December 9, 2019
- Thanks for this awesome tool! I've been using it very regularly with little to no issues and it's been super useful.— Simon (@strigona) February 8, 2020
- @getconduktor Wow, I have to just say wow. This desktop app for Kafka is simply AMAZING. Every now and then you find those cool little tools/apps that is totally impressive, here is one of those. I will gladly be buying a personal license whenever that happens.— Brandon Lamb (@brandonlamb1) January 1, 2020
- Wow! It works! Yes that's what I need! This was fast! Thank you a lot, guys, great work, the more I use Conduktor the more I like it. :-)— Ivan Ponomarev (@inponomarev) February 15, 2020
- Excellent @getconduktor . You have solved a real time problem ?? https://t.co/lc2OHqgXUm— Jenison Gracious (@JenisonGracious) February 11, 2020
- I downloaded and ran @getconduktor today. This tool is amazing. If you work with @apachekafka you NEED this tool. Great work!— Rob Hoeting (@RobHoeting) January 31, 2020
