---------------------------------------
Good point Kelly. We should fix this in the next release.
> List the ports which are required to be open in documentation.
> --------------------------------------------------------------

> Key: AMBARI-1493
> URL: https://issues.apache.org/jira/browse/AMBARI-1493
> Project: Ambari
> Issue Type: Bug
> Components: documentation
> Environment: OpenStack, AWS, anything where ports are closed by
> default
> Reporter: Issac Kelly
> Priority: Minor
> Fix For: 1.3.0
>
>
> 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
