1. Install Apache Spark 3 on Mac using Homebrew
Homebrew is a Missing Package Manager for macOS (or Linux) that is used to install third-party packages like Java, Apache Spark on Mac OS. In order to use this, first, you need to install it by using the below command.
# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This prompts for the root password. You will need to type your root password to run this command. On a personal laptop, this is the same password you enter when you log into your Mac. If you don’t have root access, contact your system admin. You should see something like this below after the successful installation of homebrew.
Post-installation, you may need to run the below command to set the brew to your $PATH.
# Set brew to Path
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/admin/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
If the above command has issues, you can find the latest command from Homebrew.
2. Install Java Version
Spark uses Java underlying hence you need to have Java on your Mac. Since Java is a third party, you can install it using the Homebrew command brew. Since Oracle Java is not open source anymore, I am using the OpenJDK version 11. Run the below command in the terminal to install it.
# Install OpenJDK 11
brew install openjdk@11
3. Install Scala
Since Apache Spark is written in Scala language it is obvious you would need Scala to run Spark programs.
# Install Scala (optional)
brew install scala
4. Install Apache Spark 3 on Mac
You can also download and install Apache Spark 3 on Mac using Homebrew. Some background about Spark, Apache Spark is an Open source analytical processing engine for large scale powerful distributed data processing and machine learning applications. Spark is Originally developed at the University of California, Berkeley’s, and later donated to Apache Software Foundation.
# Install Apache Spark
brew install apache-spark
This installs Apache Spark on your Mac OS.
After successful installation of Apache Spark run spark-shell from the command line to launch Spark shell. You should see something like this below (ignore the warning for now). spark-shell is a CLI utility that comes with Apache Spark distribution.
Note that it displays the Spark version and Java version you are using on the terminal.
5. Validate Spark 3 Installation from Shell
Let’s create a Spark DataFrame with some sample data to validate the installation. Enter the following commands in the Spark Shell in the same order.
import spark.implicits._
val data = Seq(("Java", "20000"), ("Python", "100000"), ("Scala", "3000"))
val df = data.toDF()
df.show()
Yields below output.
Now access http://localhost:4041/jobs/ from your favorite web browser to access Spark Web UI to monitor your jobs.
