For running Spark from Jupyter notebook.Reference guide for running Spark in Standalone Mode: Stop all Worker instances: sbin/stop-worker.sh or sbin/stop-slave.sh (for 2.4.6).Start a Worker instance: sbin/start-worker.sh.Hence communication between teh Master and Worker nodes should work password-less SSH configuration. Master machine accesses each of the worker machines via ssh.If conf/workers does not exist, the launch scripts defaults to a single machine (localhost).conf/workers needs to be created in Spark directory containing the host names of all the Spark worker nodes.Verify the Master Web UI: Worker instance should be listed in Workers.INFO Worker: Successfully registered with master spark://Shouviks-MacBook-Pro.local:7077 INFO TransportClientFactory: Successfully created connection to Shouviks-MacBook-Pro.local/127.0.0.1:7077 after 56 ms (0 ms spent in bootstraps)
