I need to setup a hadoop cluster (using HDP 2.6, ambari and blueprint) in a secure environment which limits the ingress/egress ports and the destinations/sources of internet traffic. For example, the hosts in this environment only open 22, 443 ports and they can only access website A, B.
To setup a hadoop cluster in such an environment, I need to know below so that ambari can work: 1. which ports need to be open. 2. which destinations/sources of internet traffic need to be permitted. Other than searching document online and try-fail-try, is there a way to get such information reliably so that I can more confidently ask people to relax the environment? Appreciate any clue.
