Good point Kelly. We should fix this in the next release.

> It took me a really, really long time to figure out which ports needed opened to have
a successful installation. 
> I opened a few too many, but here is my current list:
> DNS is open because I'm also running a DNS server in my ambari instance.  I have no idea
what 8020 is used for, but the logs of one of the nodes was trying to get to it, the 50000-60000
range is just "hadoop services" it would be nice to have a list of those somewhere as well,
so I can lock down 9990 ports or so.
> It would also be good to know which rules are just for inner-instance communication and
which should be accessible to other users, or at least a description of how each port is used,
and not just for what so that I could make those decisions for my installation.
>     rules = [
>         'icmp, -1, -1, 0.0.0.0/0',      # ping
>         'tcp, 22, 22, 0.0.0.0/0',       # ssh
>         'tcp, 53, 53, 0.0.0.0/0',       # dns
>         'udp, 53, 53, 0.0.0.0/0',       # dns
>         'tcp, 8080, 8080, 0.0.0.0/0',   # http
>         'tcp, 8440, 8441, 0.0.0.0/0',   # http, other
>         'tcp, 8020, 8020, 0.0.0.0/0',   # http, other, hadoop
>         'tcp, 5432, 5432, 0.0.0.0/0',   # postgres
>         'tcp, 50000, 60000, 0.0.0.0/0'  # hadoop, overly open
>     ]
