             Summary: Allowing files to be moved between encryption zones 
having the same encryption key
                 Key: HADOOP-15986
                 URL: https://issues.apache.org/jira/browse/HADOOP-15986
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Adam Antal


Currently HDFS blocks you from moving files from one encryption zone to 
another. On the surface this is fine, but we also allow multiple encryption 
zones to use the same encryption zone key. If we allow multiple zones to use 
the same zone key, we should also allow files to be moved between the zones. I 
believe this should be either we don't allow the same key to be used for 
multiple encryption zones, or we allow moving between zones when the key is the 
same. The latter is the most user-friendly and allows for different HDFS 
directory structures.
