I guess the first question is the threat model: What kind of bad guy are you
trying to keep out? Is Ukrainian hackers? Local users, but the servers are
locked up? Is it somebody who has physical access to the machines? Does the
information have to be secure forever or just for a while?
Once you know what you're trying to protect from, you can start thinking about
how to protect yourself.

Subject: encryption
Does anyone know of any work/ideas to encrypt data stored on hdfs?
Ideally both temporary files and final files would be encrypted. Or there would
have to be a mechanism in hdfs to securely wipe temporary files, like shred in
linux.
So far this is what i found:
