Yukun Zhou commented on IOTDB-2260:
-----------------------------------
If you want to execute "REVOKE admin FROM xzh_02", you need to "grant user dddd
privileges REVOKE_USER_ROLE on root". This is not a bug. It's just a confusing
feature.
> When the authorized user cancels the permission of a user, which still
> reports has no permission
