Thanks, I’m just using RStudio. Running locally is fine, just issue with having cluster in Linux and workers looking for Windows path, Which must be being passed through by the driver I guess. I checked the spark-env.sh on each node and the appropriate SPARK_HOME is set correctly….

Could you check the values of “SPARK_HOME” environment on all of your worker nodes? 2. How did you start your SparkR shell?

If so, I’d appreciate someone letting me know what I need to change/set.
