Nice. Two nits, but other than that, I'm +1.

FSN:

  * @param keyName name of a key present in the configured KeyProvider.

s/present/which must be present/

TestEncryptionZones:

whitespace (extra newline).

> Currently, when creating an encryption zone, if the user does not specify a 
> key name, the NN will generate a new one with a UUID. This leads to opaque 
> names, and there's no way to specify further key creation attributes. Simpler 
> and better is to make the admin first create the key however they like (e.g. 
> via "hadoop key") and then specify it when creating a zone.
