> This is the first step toward better "Scratch space" and "Soft Delete" 
> support. We remove the assumption that the hdfs directory and encryption zone 
> is 1 to 1 mapped and can't be changed once created.
> The encryption zone creation part is kept As-Is from Hadoop 2.4. We 
> generalize the encryption zone and its directories from 1:1 to 1:many. This 
> way, other directories such as scratch can be added to/removed from 
> encryption zone as needed. Later on, files in these directories can be 
> renamed within the same encryption zone efficiently.
