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.
