Greetings to all, I've search around the mailing list, but it would seem that (nearly?) everyone has the opposite problem as mine. I made a stab at looking in the source for an answer, but I figured I might as well see if anyone else has run into the same problem as I.
I'm trying to limit my Master/Worker UI to run only on localhost. As it stands, I have the following two environment variables set in my spark-env.sh: SPARK_LOCAL_IP=127.0.0.1 SPARK_MASTER_IP=127.0.0.1 and my slaves file contains one line: 127.0.0.1 The problem is that when I run "start-all.sh", I can nmap my box's public interface and get the following: PORT STATE SERVICE 22/tcp open ssh 8080/tcp open http-proxy 8081/tcp open blackice-icecap Furthermore, I can go to my box's public IP at port 8080 in my browser and get the master node's UI. The UI even reports that the URL/REST URLs to be 127.0.0.1: Spark Master at spark://127.0.0.1:7077 URL: spark://127.0.0.1:7077 REST URL: spark://127.0.0.1:6066 (cluster mode) I'd rather not have spark available in any way to the outside world without an explicit SSH tunnel. There are variables to do with setting the Web UI port, but I'm not concerned with the port, only the network interface to which the Web UI binds. Any help would be greatly appreciated.
