Subject [jira] [Commented] (HDFS-6134) Transparent data at rest encryption
Date Wed, 25 Jun 2014 18:36:29 GMT

Owen O'Malley commented on HDFS-6134:
-------------------------------------

Owen, that is NOT transparent.

Transparent means that you shouldn't have to change your application code. Hacking HDFS to
add encryption is transparent for one set of apps, but completely breaks others. Changing
URLs requires no code changes to any apps.

> Because of privacy and security regulations, for many industries, sensitive data at rest
must be in encrypted form. For example: the health­care 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.
