Correct answer: Scala code will be executed inside the Spark JVM (per machine) that is shared between all users, so you can get access to everything that is inside JVM. https://learn.microsoft.com/en-us/answers/questions/924587/azure-databricks-scala-on-high-concurrency-cluster.html High Concurrency clusters can run workloads developed in SQL, Python, and R. The performance and security of High Concurrency clusters is provided by running user code in separate processes, which is not possible in Scala. https://learn.microsoft.com/en-us/azure/databricks/clusters/configure#--high-concurrency-clusters
