Tsz Wo Nicholas Sze commented on HDFS-6134:
-------------------------------------------

Nice doc!

For #3 HDFS Encryption (Client Side), if the keys are available in NN, are the 
keys encrypted?  Otherwise, a malicious admin could possibly dump the NN memory 
in order to obtain the keys.  I think we should clarify how to encrypt the keys 
in NN in the doc.

For #4, the keys are available in DNs for encrypting the data, i.e. the keys 
must not be encrypted.  A malicious admin definitely could obtain the keys by 
dumping the DN memory.  So #4 does not work.

> 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.
