That is a very appropriate setup. As long as those assumptions remain valid, of
course. This was the only way how early hadoop clusters were secured - by
restricting access to the cluster using firewall and gateways.

Hey Haohui,
Thanks for responding. I understand that I can disable security. I am
wondering if I should in this situation. Or to turn the question around: is
there a significant benefit to turning security on here?

Hi Koert,
I'm wondering what is the end-to-end goal you want to achieve.
You can disable security in Hadoop, where the cluster does not perform
additional authentication. Obviously you can go without kerberos in this
case and protect your clusters with other measures you've mentioned.
Alternativ
i understand kerberos is used on hadoop to provide security in a multi-user
environment, and i can totally see its usage for a shared cluster within a
company to make sure sensitive data for one department is safe from prying
eyes of another department.
but for a hadoop cluster that sits "behind"
