Zhe Zhang updated HDFS-9688: ---------------------------- Attachment: HDFS-9688-branch-2.8.02.patch Thanks for the update [~aw]. I discussed with Andrew offline, this patch should actually be targeted for 2.8, and future maint releases of 2.6 and 2.7. Attaching a branch-2.8 patch. [~andrew.wang] Could you take another look? A tricky issue is "rename of root dir of EZ". I just found it's not allowed in 2.6, but allowed in 2.7 and forward. So we need to update the patch when backporting to 2.6. Also, renaming the root dir of a nested EZ won't be allowed, because the destination will be in an EZ (the parent EZ). I think this is the right behavior for nested EZ, but please see if you agree. > Test the effect of nested encryption zones in HDFS downgrade > ------------------------------------------------------------ > > Key: HDFS-9688 > URL: https://issues.apache.org/jira/browse/HDFS-9688 > Project: Hadoop HDFS > Issue Type: Test > Components: encryption, test > Reporter: Zhe Zhang > Assignee: Zhe Zhang > Attachments: HDFS-9688-branch-2.6.00.patch, > HDFS-9688-branch-2.6.01.patch, HDFS-9688-branch-2.8.02.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
