---------------------------------

             Summary: Can't write tight firewall rules for Spark
                 Key: SPARK-2157
                 URL: https://issues.apache.org/jira/browse/SPARK-2157
             Project: Spark
          Issue Type: Bug
          Components: Deploy, Spark Core
    Affects Versions: 1.0.0
            Reporter: Andrew Ash
            Priority: Critical


In order to run Spark in places with strict firewall rules, you need to be able to specify every port that's used between all parts of the stack.

Per the [network activity section of the docs|http://spark.apache.org/docs/latest/spark-standalone.html#configuring-ports-for-network-security] most of the ports are configurable, but there are a few ports that aren't configurable.

We need to make every port configurable to a particular port, so that we can run Spark in highly locked-down environments.
