The Master Spark REST URL is on port 6066 by default. So you should see this as your Master endpoint: spark://172.20.9.151:6066.

If you go the to Spark web console (http://master:8080) you will get the details of the various endpoints of your cluster.

    Why does it require REST URL? Aren't we supposed to give spark, master URL, the one generally running on port 7077? – shanti Feb 23 '18 at 02:08
