Vertica Installation Issue : Prerequisites not fully met during local (OS) configuration

adarshchandrarai

Guys, I am in the process of Installing Vertica for one of my Application and facing the following issue.

Prerequisites not fully met during local (OS) configuration for
verify-172.16.239.221.xml:
WARN (N0010): https://www.vertica.com/docs/9.2.x/HTML/index.htm#cshid=N0010
Linux iptables (firewall) has some non-trivial rules in tables: mangle,
filter
System prerequisites failed. Threshold = WARN
Hint: Fix above failures or use --failure-threshold
Installation FAILED with errors.

---

AdminTools and your existing Vertica databases may be unavailable.
Investigate the above warnings/errors and re-run installation.

****

Any leads will be really helpful.

Issue is that Vertica requires certain TCP and UDP ports, but the installation script lacks the logic to check all possible iptables rules to make sure they are valid.
Please review the network requirements posted at https://www.vertica.com/docs/9.3.x/HTML/Content/Authoring/InstallationGuide/BeforeYouInstall/EnsurePortsAreAvailable.htm
The port requirements are same for all 9.x and 10.x versions. If you are sure that Vertica will be able to access all of the listed ports, then you can proceed with install by setting "--failure-threshold NONE" to bypass this message.
