My initial guess is that it's a security group setting and/or that you
are lacking a public IP associated with the setup. You can have
Starcluster running on a private subnet, but if you do that you need to
have your NAT setup properly with connections to your Starcluster
cluster. If you are running on a no longer supported version of the OS
like Phil suggested that also is going to cause an issue and you won't
be able to install the packages you need. If this is the case use the
AMI for Ubuntu 12.04 as he suggested. If you need 14.04, upgrade the
12.04 to 14.04 and/or you can take a whirl at using the directions I
sent yesterday with getting Starcluster to run on Ubuntu 14.04 LTS as
provided by Ubuntu.com.
If it isn't the OS, the solution can get complicated so a quick fix
might be just to save an AMI of master node you have right now. Launch
that AMI as a new EC2 instance under the default VPC that AWS provides
(this allows you to connect to the internet and provides public IP).
Login to that new EC2 instance and add all the software you need for
your Starcluster cluster ( including R) and update the OS with the
latest security patches. Stop the instance and save it as an AMI, use
this new AMI (that includes R and OS security patches) to create your
Starcluster cluster as you had originally. Problem solved you have R
and software you need on a running Starcluster cluster.
Good Luck!
