Kafka Installation and Test Broker Setup

In this post we will discuss about Kafka Installation and Test Broker Setup in Ubuntu machine in a stand-alone zookeeper mode.

Apache Kafka:

Open Source Message Broker from Apache Software Foundation.  Initially developed at LinkedIn and later contributed to Open-source community. It is written in Scala.

Kafka Provides a unified, high-throughput, low-latency platform for handling real-time data feeds.

Types of data being transported through Kafka?

  • Metrics: operational telemetry data
  • Tracking: everything a LinkedIn.com user does
  • Queuing: between LinkedIn apps, e.g. for sending emails


Why is Kafka so fast?

Fast writes:

  • While Kafka persists all data to disk, essentially all writes go to thepage cache of OS, i.e. RAM.
  • Cf. hardware specs and OS tuning (we cover this later)

Fast reads:

  • Very efficient to transfer data from page cache to a network socket
  • Linux: sendfile() system call

Example (Operations): On a Kafka cluster where the consumers are mostly caught up you will see no read activity on the disks as they will be serving data entirely from cache.

Core ComponentsKafka Architecture


  • Topics, partitions, replicas, offsets
  • Producers, brokers, consumers
  • Producers write data to brokers.
  • Consumers read data from brokers.
  • All this is distributed.
  • Data is stored in topics.
  • Topics are split into partitions, which are replicated.

Step 1: Download

First download latest statble verion of kafka from Apache Download Mirrors . In this post we are installing kafka_2.11- and untar it into /usr/lib/kafka folder.

Step 2:

Add below entries into .bashrc file

### kafka Home directory ####

Step 3 : Start ZooKeeper

Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don’t already have one. You can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance.

Step 4: Start the Kafka Server

Open another terminal and start Kafka Server

Step 5: Create Test Topic

Open another terminal. Create a topic named “test” with a single partition and only one replica:

Use the below list command to view the topic

Run the producer and then type a few messages into the console to send to the consumer.

Step 6 : Start Consumer

Open another terminal and see producers messages being Consumed

If you receive messages like above, You have successfully setup Kafka Console Producer and Consumer.
