Subject [jira] [Created] (HDFS-8830) Support add/remove directories to an existing encryption zone
Date Tue, 28 Jul 2015 19:54:04 GMT
Xiaoyu Yao created HDFS-8830:

             Summary: Support add/remove directories to an existing encryption zone
                 Key: HDFS-8830
                 URL: https://issues.apache.org/jira/browse/HDFS-8830
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao

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.
