[~jsnowacki] I didnt say parenthesis is the root cause just saying to correct
it in the description... Ok now it makes more sense.
Btw there is a fix here for overriding confs:
https://issues.apache.org/jira/browse/SPARK-15520 but probably this would not
help. Anyway I would suggest you just add in the description that this is
reproducible in Jupyter.

> Config spark.jars.packages is ignored in SparkSession config
> ------------------------------------------------------------
>
> Key: SPARK-21752
> URL: https://issues.apache.org/jira/browse/SPARK-21752
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Jakub Nowacki
>
> If I put a config key {{spark.jars.packages}} using {{SparkSession}} builder
> as follows:
> {code}
> spark = pyspark.sql.SparkSession.builder\
> .appName('test-mongo')\
> .master('local[*]')\
> .config("spark.jars.packages",
> "org.mongodb.spark:mongo-spark-connector_2.11:2.2.0")\
> .config("spark.mongodb.input.uri", "mongodb://mongo/test.coll") \
> .config("spark.mongodb.output.uri", "mongodb://mongo/test.coll") \
> .getOrCreate()
> {code}
> the SparkSession gets created but there are no package download logs printed,
> and if I use the loaded classes, Mongo connector in this case, but it's the
> same for other packages, I get {{java.lang.ClassNotFoundException}} for the
> missing classes.
> If I use the config file {{conf/spark-defaults.comf}}, command line option
> {{--packages}}, e.g.:
> {code}
> import os
> os.environ['PYSPARK_SUBMIT_ARGS'] = '--packages
> org.mongodb.spark:mongo-spark-connector_2.11:2.2.0 pyspark-shell'
> {code}
> it works fine. Interestingly, using {{SparkConf}} object works fine as well,
> e.g.:
> {code}
> conf = pyspark.SparkConf()
> conf.set("spark.jars.packages",
> "org.mongodb.spark:mongo-spark-connector_2.11:2.2.0")
> conf.set("spark.mongodb.input.uri", "mongodb://mongo/test.coll")
> conf.set("spark.mongodb.output.uri", "mongodb://mongo/test.coll")
> spark = pyspark.sql.SparkSession.builder\
> .appName('test-mongo')\
> .master('local[*]')\
> .config(conf=conf)\
> .getOrCreate()
> {code}
> The above is in Python but I've seen the behavior in other languages, though,
> I didn't check R.
> I also have seen it in older Spark versions.
> It seems that this is the only config key that doesn't work for me via the
> {{SparkSession}} builder config.
