Subject Submitting Spark Applications - Do I need to leave ports open?
Date Mon, 26 Oct 2015 20:35:48 GMT
I want to submit interactive applications to a remote Spark cluster running
in standalone mode. 

I understand I need to connect to master's 7077 port. It also seems like the
master node need to open connections to my local machine. And the ports that
it needs to open are different every time. 

If I have firewall enabled on my local machine, spark-submit fails since the
ports it needs to open on my local machine are unreachable, so spark-submit
fails to connect to the master. 

I was able to get it to work if i disable firewall on my local machine. But
that's not a real solution. 

Is there some config that I'm not aware of that solves this problem?
