Pyspark setup for IntelliJ IDEA

on 2021-01-24

Simple configuration of a new Python IntelliJ IDEA project with working pyspark. I was inspired by "Pyspark on IntelliJ" blog post by Gaurav M Shah, I just removed all the parts about deep learning libraries. I assume that you have a working IntelliJ IDEA IDE with Python plugin installed, and Python 3 installed on your machine. We will create a Python project in IntelliJ IDEA, change its Python SDK to a virtualenv based Python SDK, add Pyspark dependency to this VirtualEnv, install Pyspark in this VirtualEnv and finally test it using a small Pyspark hello world.
