I am getting a class not found error
import org.apache.spark.SparkContext
It sounds like this is because pyspark is not installed, but as far as I
can tell it is.
Pyspark is installed in the correct python verison
root@namenode:/home/spark/# pip3.10 install pyspark
Requirement already satisfied: pyspark in
/usr/local/lib/python3.10/dist-packages (3.4.1)
Requirement already satisfied: py4j==0.10.9.7 in
