Why would the Executors shutdown when the Job is terminated? Executors are bound to Applications, not Jobs. Furthermore, unless spark.job.interruptOnCancel is set to true, canceling the Job at the Application and DAGScheduler level won't actually interrupt the Tasks running on the Executors. If you do have interruptOnCancel set, then you can catch the interrupt exception within the Task.
