Pycharm + Pyspark error - java.util.NoSuchElementException: key not found: _PYSPARK_DRIVER_CALLBACK_HOST

i'm using PyCharm 2019.1, and Python 3.7 (in Project Interpreter) On PyCharm, i've added Pyspark 2.4.2

when i run the following code (to create a Spark DataFrame), i get error

java.util.NoSuchElementException: key not found: _PYSPARK_DRIVER_CALLBACK_HOST
....
Exception: Java gateway process exited before sending its port number

from the other SO issues, it seems that it is related to version mismatch, question is how to resolve this

my $SPARK_HOME points to Apache Spark 2.2.0

CODE => 

from pyspark.sql import SparkSession

d = {'a':1, 'b':2, 'c':3}

spark = SparkSession.builder.master("local").appName("CreatingDF").getOrCreate()

pandaDF = spark.createDataFrame(d)
print(pandaDF)  

ERROR ->

Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
