Nicholas Chammas created SPARK-2528:
---------------------------------------
Summary: spark-ec2 security group permissions are too open
Key: SPARK-2528
URL: https://issues.apache.org/jira/browse/SPARK-2528
Project: Spark
Issue Type: Bug
Components: EC2
Affects Versions: 1.0.0
Reporter: Nicholas Chammas
Priority: Minor
{{spark-ec2}} configures EC2 security groups with ports [open to the world |
https://github.com/apache/spark/blob/master/ec2/spark_ec2.py#L280]. This is an
unnecessary security risk, even for a short-lived cluster.
Wherever possible, it would be better if, when launching a new cluster,
{{spark-ec2}} detects the host's external IP address (e.g. via
{{icanhazip.com}}) and grants access specifically to that IP address.
