I am trying to run a spark session in the Jupyter Notebook on a EC2 Linux machine via Visual Studio Code. My code looks as following:
from pyspark.sql import SparkSession
spark = SparkSession.builder.appName("spark_app").getOrCreate()
the error is:
{
"name": "Py4JError",
"message": "An error occurred while calling None.org.apache.spark.sql.SparkSession.

I have googled a lot without a success. Does anybody has an idea what is wrong?
I use IPython Kernel with 3.9 Python installed.
