--------------------------------

Hi,Heng Chen
if the client needs to modify these node, and you trust it, i think you can 
grant auth to it manually.


> there need be a mechanism to enable ZK's ACL check when the authentication 
> strategy is simple

> if the hbase.security.authentication is set to simple, the ZKUtil.createACL 
> just return Ids.OPEN_ACL_UNSAFE, means that there is no ACL check on the ZK's

> we can refactoring this to enables the ACL's check function
> manual steps to verify the patch
