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.
