init Exception: Java gateway process exited before sending its port number

Question

Code is below

import findspark
findspark.init(r'C:UsersuserDocumentsspark-3.0.0-bin-hadoop2.7')
import pyspark
from pyspark.sql import SparkSession
spark = SparkSession.builder.appName('Basics').getOrCreate()

Got error
Exception: Java gateway process exited before sending its port number

Disclaimer: Already added JAVA_HOME to env variables, I didnt needed to add spark as i am calling init

Already went through so many links to check the error could not resolve

Answer 1

What’s your Java version? Adding JAVA_HOME to your path won’t help if you’ve got a non-compatible version of Java. Java v8 is by far the easiest to get running but the docs say that you should be able to get v11 running.

Answer 2

For me the fix was to call the process with spark-submit name_of_spark_file.py
I believe it would also work with scala files.
