Hi, Your mileage varies so to speak.Whether or not the data you use to analyze in Spark through RStudio will be seen by Spark's back-end depends on how you deploy Spark and RStudio. If you are deploying Spark and RStudio on your own premises or in a private cloud environment, then the data you use will only be accessible to the roles that have access to your environment. However, if you are using a managed Spark service such as Google Dataproc or Amazon EMR etc, then the data you use may be accessible to Spark's back-end. This is because managed Spark services typically store your data on their own servers. Try using encryption combined with RBAC (who can access what), to protect your data privacy. Also beware of security risks associated with third-party libraries if you are deploying them.
