I'm trying to get a pyspark script running remotely on AWS EMR, following the instructions provided by AWS. However, when I try to submit my script, I am getting the following exception:

I have SPARK_HOME set to the directory where I uncompressed Spark, and I can see that it does contain some Jars:
$ echo $SPARK_HOME
/home/aco/Downloads/spark-2.4.0-bin-hadoop2.7
$ ls $SPARK_HOME/jars | head
activation-1.1.1.jar
aircompressor-0.10.jar
antlr-2.7.7.jar
antlr4-runtime-4.7.jar
antlr-runtime-3.4.jar
aopalliance-1.0.jar
aopalliance-repackaged-2.4.0-b34.jar
apacheds-i18n-2.0.0-M15.jar
apacheds-kerberos-codec-2.0.0-M15.jar
apache-log4j-extras-1.2.17.jar
I don't really have any clue how to debug this. Any ideas?
