So I've been looking into options for providing encryption at rest, and it
seems like what Accumulo has is abandonware from a project perspective.
There is no official documentation on how to perform encryption at rest,
and the best information from its status comes from year (or greater) old
ticket comments about how the feature is still experimental. Recently there
was a talk that described using HDFS encryption zones as an alternative.
From my perspective, this is what I see as the current situation:
1- Encryption at rest in Accumulo isn't actively being worked on
2- Encryption at rest in Accumulo isn't part of the public API or marketed
capabilities
3- Documentation for what does exist is scattered throughout Jira comments
or presentations
4- A viable alternative exists that appears to have feature parity in HDFS
encryption
5- HBase has finer grained encryption capabilities that extend beyond what
HDFS provides
Moving forward, what's the consensus for supporting this feature?
Personally, I see two options:
1- Start going down a path to bring the feature into the forefront and
start providing feature parity with HBase
or
2- Remove the feature and place emphasis on upstream encryption offerings

I'm only smart enough to know that I'm not smart enough to build a
distributed database *and* encrypt it securely. I'd much prefer to defer
to the people up the stack.
The one thing we'd miss out on is things like column-family-level
encryption control (which I think HBase has), but I'd much rather have a
complete encryption story before worrying about the fine-grained support.
Any input is welcomed& appreciated!
