   > Ozone supports Ranger Authorizer for ACLs and whitelisting users to access 
all keys can easily be achieved by creating a Ranger policy or adding users to 
an existing Ranger policy. For Ozone native authorizer, we already have 
ozone.administrators who should be able to access all keys. I don't understand 
the need for this new white list.

   Hi @vivekratnavel, Very thanks for your discussion. Your tips are very 
helpful for me.
       Currently, ranger is not enabled in our cluster, we use native acl. 
Ozone Administrators might overlap with this whitelist. Instead of adding a 
white list, we can improve the functionality of Ozone Administrators.
       After testing, I found that the current ozone Administrators cannot 
access all keys. Administrators of ozone are also checked for permissions. Is 
this a bug? In HDFS, Administrators can able to access all files,and HDFS does 
not check permissions of Administrators.
       I can change this PR to make sure Administrators can access all keys.
