Trying to open spark after installation and getting an error: Unable to find any JVMs matching version "1.8"

Description:

I installed spark on my MacBook following using Homebrew. I followed the instruction process from: https://www.tutorialkart.com/apache-spark/how-to-install-spark-on-mac-os/.

The step by step process included installing Java, followed by Scala and then Spark. Java and Scala got installed successful. Spark got installed successfully as well.

When I tried to verify spark installation using below input command, I ran into an error.

Input command: spark-shell

Expected Behavior: Expect Spark to start on terminal

Actual Behavior: I get this below error:

Unable to find any JVMs matching version "1.8".

What I tried:

I tried to change JAVA_HOME using below commands:

export JAVA_HOME=/usr/local/opt/java

Previous JAVA_HOME path was /opt/anaconda3. I can see that JAVA_HOME got changed to usr/local/opt/java.

I am still getting the error. Appreciate your answers/feedback. Thanks!!!

Follow these steps for macOS
Step 1. install java 8 as Spark 2.2 onwards requires java8. See Spark Documentation! for details.
> brew install openjdk@8

Then set update java path
> export JAVA_HOME=/usr/local/opt/openjdk@8/libexec/openjdk.jdk/Contents/Home

I was searching across the web and saw instructions to install pyspark.

I ran this command pip install pyspark on Terminal

After I installed pyspark, both spark and pyspark are running.

Not sure what happened, but I am able to run spark now.

Thanks @Elliott for interacting and giving some directions!
