1. You can comment the rest of the workers from the conf/slaves file and do a stop-slaves.sh from that machine to stop the specific worker.
2. There is no direct command for it, but you can do something like the following: $ curl localhost:8080 | grep "Applications" -C 10 | head -n20 Where localhost is your master machine and 8080 is the web ui port. You can also look at the metrics <http://spark.apache.org/docs/latest/monitoring.html#metrics> options for more sophisticated version.
