How to Check Apache Kafka Version?

Apache Kafka is a distributed streaming platform that can be used to process real-time data. It is a popular choice for applications such as event streaming, log aggregation, and data integration.

One of the most important things to know about Kafka is its version. The version number tells you what features are supported and what kind of performance you can expect. It also helps you to troubleshoot problems and identify compatibility issues.

In this article, we will show you how to check the version of Kafka on your cluster. We will also provide some tips on how to upgrade Kafka to the latest version.

Prerequisites

To follow along with this tutorial, you will need the following:

  • A Kafka cluster running on one or more machines
  • The `kafka-topics` CLI tool
  • The `kafka-version` CLI tool

    Step Command Explanation
    1 kafka-version This command will print the version of Apache Kafka that is currently running.
    2 kafka-topics.sh --version This command will print the version of the Kafka Topics CLI tool.
    3 kafka-consumer-groups.sh --version This command will print the version of the Kafka Consumer Groups CLI tool.

    Apache Kafka is a distributed streaming platform that allows you to build real-time applications. It is used by companies such as Netflix, Uber, and Spotify to process large amounts of data in real time.

    One of the most important things to know about Kafka is its version. The version number tells you what features are supported and what bugs have been fixed. It is important to make sure that you are using the latest version of Kafka so that you can take advantage of the latest features and bug fixes.

    In this tutorial, you will learn how to check the Kafka version using the CLI.

    Check the Kafka Version Using the CLI

    To check the Kafka version using the CLI, you can use the following command:

    kafka-version

    This command will print the Kafka version to the console.

    For example, the following output shows that the Kafka version is 2.8.0:

    Kafka version: 2.8.0

    You can also use the following command to get more information about the Kafka version:

    kafka-topics –version

    This command will print the Kafka version and the version of the ZooKeeper server that Kafka is using.

    For example, the following output shows that the Kafka version is 2.8.0 and the ZooKeeper version is 3.4.14:

    Kafka version: 2.8.0
    ZooKeeper version: 3.4.14
