Jordan Zimmerman commented on ZOOKEEPER-2779:
---------------------------------------------
lol - we're going in circles. Your statement about "online" vs "offline"
doesn't hold water. Forcing "super user" to make reconfig changes was - pardon
my frankness - a very bad plan. It is a step backwards in security. The older
method is much more secure when handled properly. Anyway, if you'll merge this
change it would make us very happy.
> Add option to not set ACL for reconfig node

> Project: ZooKeeper

>
> ZOOKEEPER-2014 changed the behavior of the /zookeeper/config node by setting
> the ACL to {{ZooDefs.Ids.READ_ACL_UNSAFE}}. This change makes it very
> cumbersome to use the reconfig APIs. It also, perversely, makes security
> worse as the entire ZooKeeper instance must be opened to "super" user while
> enabled reconfig (per {{ReconfigExceptionTest.java}}). Provide a mechanism
> for savvy users to disable this ACL so that an application-specific custom
> ACL can be set.
