Stephen Chu created HDFS-6951:
---------------------------------
Summary: Saving namespace and restarting NameNode will remove
existing encryption zones
Key: HDFS-6951
URL: https://issues.apache.org/jira/browse/HDFS-6951
Project: Hadoop HDFS
Issue Type: Sub-task
Components: encryption
Affects Versions: 3.0.0
Reporter: Stephen Chu
Fix For: 3.0.0
Attachments: HDFS-6951-testrepo.patch
Currently, when users save namespace and restart the NameNode, pre-existing
encryption zones will be wiped out.
To reproduce:
* Create an encryption zone
* List encryption zones and verify the newly created zone is present
* Save the namespace
* Kill and restart the NameNode
* List the encryption zones and you'll find the encryption zone is missing
I've attached a test case for {{TestEncryptionZones}} that reproduces this as
well. Removing the saveNamespace call will get the test to pass.
