How to add jar to Spark in Pycharm

Question

I want to debug Spark code in PyCharm because it is easier to debug. But I need to add a spark-redis.jar otherwise Failed to find data source: redis

The code to connect to redis is

spark = SparkSession \
            .builder \
            .appName("Streaming Image Consumer") \
            .config("spark.redis.host", self.redis_host) \
            .config("spark.redis.port", self.redis_port) \
            .getOrCreate()

How to do fix it if using PyCharm?

I have tried adding spark.driver.extraClassPath in $SPARK_HOME/conf/spark-defaults.conf but it does not work.

I also tried adding environment variable PYSPARK_SUBMIT_ARGS --jars ... in run configuration but it raise other error

Answer 1

Adding spark.driver.extraClassPath to spark-defaults.conf works for me with Spark 2.3.1

cat /Users/oleksiidiagiliev/Soft/spark-2.3.1-bin-hadoop2.7/conf/spark-defaults.conf

spark.driver.extraClassPath /Users/oleksiidiagiliev/.m2/repository/com/redislabs/spark-redis/2.3.1-SNAPSHOT/spark-redis-2.3.1-SNAPSHOT-jar-with-dependencies.jar

Please note, this is a jar with dependencies (you can build one from sources using mvn clean install -DskipTests ).

Aslo I added pyspark libraries and SPARK_HOME environment variable to PyCharm project as described here https://medium.com/parrot-prediction/integrating-apache-spark-2-0-with-pycharm-ce-522a6784886f
