Andrew Ash created SPARK-2157:
---------------------------------
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.
