Should I enable iptable / firewalld after Ambari completes setup

Should I enable iptable / firewalld after Ambari completes setup

Contributor

I'm following the instruction here in installing Ambari:

http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-installation/content/configuring_i...

Since I'm using RHEL 7.2, I am issuing the commands

$ systemctl disable firewalld 
$ service firewalld stop

Obviously leaving the firewall open poses a security risk. After I complete my Ambari setup and installation, and assuming I'm running all the services that I want to be there, can I enable then the firewall again without affecting Ambari? If enabling it affects Ambari's functioning, what can be done to get the firewall up again and still keep Ambari working smoothly.

Some ports need to be opened for an ecosystem component or service to communicate with other components and services.
