How to specify --jars in spark-submit? - apache-spark

Question

I want to add a couple of gcs connector jars to spark-submit. These will allow my spark application to read files from google storage.
I can do the following in python:
from pyspark import pandas as pd
spark = SparkSession.builder.config("spark.jars","/usr/local/share/google/dataproc/lib/gcs-connector.jar,/usr/l
ocal/share/google/dataproc/lib/gcs-connector-hadoop3-2.2.3.jar").getOrCreate()
pd.read_csv("gs://monsoon-credittech.appspot.com/mar19/training_data.csv",nrows=2)
But, I cannot achieve the same with spark-submit utility
spark-submit --master yarn --jars /usr/local/share/google/dataproc/lib/gcs-connector-hadoop3-2.2.3.jar, /usr/local/share/google/dataproc/lib/gcs-connector.jar testing_dep.py --num 2 --path gs://monsoon-credittech.appsp
ot.com/mar19/training_data.csv
output:
2022-01-08 16:34:43,605 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Why is the spark-submit asking me to provide --class. My entry point is testing_dep.py. I do not have --class to be specified. How can I achieve adding those jars?
