Hi Jonathan, Thanks for the information. If you're able, could you also try the 'SPARK_CLASSPATH' environment variable instead of the spark-defaults.conf setting, and let us know if that works? Also the exact Spark package you're using would be helpful as well (from source, prebuilt for 2.6+, 2.4+, CDH, etc.)
