Bhupendra Kumar Jain commented on ZOOKEEPER-2591:
-------------------------------------------------

Right, But What if the malicious user deletes this node as soon as its get created. In that case the applications which tries to create children inside this parent node will fail. Its rare case but quite possible.

> Container nodes check the ACL before creation, but the deletion doesn't check  the ACL rights. The code below succeeds even tough we removed ACL access permissions for "/a".
> {code}
>         zk.create("/a", null, Ids.OPEN_ACL_UNSAFE, CreateMode.CONTAINER);
>         ArrayList<ACL> list = new ArrayList<>();
>         list.add(new ACL(0, Ids.ANYONE_ID_UNSAFE));
>         zk.setACL("/", list, -1);
>         zk.delete("/a", -1);
> {code}
