             Summary: Maintain a list of all the Encryption Zones in the file system
                 Key: HDFS-6457
                 URL: https://issues.apache.org/jira/browse/HDFS-6457
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode, security
            Reporter: Charles Lamb


We need to maintain a list of all encryption zones in the file system so that we can ask questions about what EZ a path belongs to, if any, and let the admin know all the EZs in the system.

[~andrew.wang] Why not just have a sorted structure with pointers to all the roots of the EZs? We can populate it during metadata loading on startup, and keep it updated during runtime.
