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 Any input is welcomed & appreciated!
