Todd Lipcon commented on HDFS-6134:
-----------------------------------
I think the "solution" to this issue is by administrative policy - eg no single
person has root access to the machine. Two admins each know half of the
password, and thus neither can log in without the other one watching over their
shoulder. (or some equivalent thereof using split key based access, etc).

> Key: HDFS-6134
> URL: https://issues.apache.org/jira/browse/HDFS-6134
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: security
> Affects Versions: 2.3.0
> Reporter: Alejandro Abdelnur

> Because of privacy and security regulations, for many industries, sensitive
> data at rest must be in encrypted form. For example: the healthÂcare industry
> (HIPAA regulations), the card payment industry (PCI DSS regulations) or the
> US government (FISMA regulations).
> This JIRA aims to provide a mechanism to encrypt HDFS data at rest that can
> be used transparently by any application accessing HDFS via Hadoop Filesystem
> Java API, Hadoop libhdfs C library, or WebHDFS REST API.
> The resulting implementation should be able to be used in compliance with
> different regulation requirements.
