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

             Summary: Open ports in spark-ec2.py to allow HDFS NFS gateway  
                 Key: SPARK-6600
                 URL: https://issues.apache.org/jira/browse/SPARK-6600
             Project: Spark
          Issue Type: New Feature
          Components: EC2
            Reporter: Florian Verhein



Use case: User has set up the hadoop hdfs nfs gateway service on their 
spark-ec2.py launched cluster, and wants to mount that on their local machine. 

Requires the following ports to be opened on incoming rule set for MASTER for 
both UDP and TCP: 111, 2049, 4242.
(I have tried this and it works)

Note that this issue *does not* cover the implementation of a hdfs nfs gateway 
module in the spark-ec2 project. That should be a separate issue (TODO).
