Subject [jira] Created: (HADOOP-6444) Support additional security group option in hadoop-ec2 script

Support additional security group option in hadoop-ec2 script
-------------------------------------------------------------

                 Key: HADOOP-6444
                 URL: https://issues.apache.org/jira/browse/HADOOP-6444
             Project: Hadoop Common
          Issue Type: Improvement
          Components: contrib/ec2
            Reporter: Paul Egan
            Priority: Minor


When deploying a hadoop cluster on ec2 alongside other services it is very useful to be able
to specify additional (pre-existing) security groups to facilitate access control.  For example
one could use this feature to add a cluster to a generic "hadoop" group, which authorizes
hdfs access from instances outside the cluster.  Without such an option the access control
for the security groups created by the script need to manually updated after cluster launch.
