Installing Apache Kafka

You can set up Apache Kafka by using brew or downloading the binary.

Installing via Binary Download

1.) Go to apache kafka site

2.) Under Binary downloads, download
    "Scala 2.12  - kafka_2.12-2.0.0.tgz (asc, sha512)"

3.) Open a terminal, move the downloaded file to the root directory then extract
     mv Downloads/kafka_2.12-2.0.0.tgz .
     tar -xvf kafka_2.12-2.0.0.tgz

4.) Verify if it works
      cd kafka_2.12-2.0.0
      bin/kafka-topics.sh

    4.1) (If it doesn't work)
          brew tap caskroom/versions
          brew cask install java8

Installing Kafka via Brew

1.)  Open a terminal,

      brew install kafka

      (That's it)

Note: The one notable difference between installing via brew vs binary is that if you install by brew,

          there's no need to add the .sh extension to run kafka commands
