Subject [DISCUSS] What to do about encryption at rest?
Date Fri, 30 Oct 2015 20:22:44 GMT
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
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
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


2- Remove the feature and place emphasis on upstream encryption offerings

Any input is welcomed & appreciated!
