from pyspark import SparkConf
from pyspark.sql import SparkSession

appName = "Python Example - Pass Environment Variable to Executors"
master = 'yarn'

# Create Spark session
conf = SparkConf().setMaster(master).setAppName(
    appName).setExecutorEnv('ENV_NAME', 'ENV_Value')

spark = SparkSession.builder.config(conf=conf) \
    .getOrCreate()
