----------------------------------
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.
