Looking at the [implementation notes](https://github.com/apache/zookeeper/pull/1106#issue-501722487), it appears that there is only one watcher created on the server-side. It says: > PathParentIterator is the "meat" of the implementation. Rather than set watchers on every ZNode implied by a recursive watcher. WatchManager passes any paths it processes through PathParentIterator which iterates up each parent znode looking for watchers. -- This is an automated message from the Apache Git Service.
