Re: Znode ACL watcher?
Thanks guys. I don't have a strong use case but it did seem something of an oddity/incompleteness when I was implementing the eclipse plug-in to dynamically respond to znode changes. Without a Watcher available, it means that ACL changes are the one instance where a user has to manually click "Refresh" to see the latest version. This is clearly a UI-centric example, but I am not aware of any *normal* use cases where this would be an issue.

Feel free to enter JIRA(s) if you feel strongly. I agree with Ben in the sense that I haven't heard of any use cases that require this, but a JIRA with examples might strengthen the case.

Re: Znode ACL watcher?
no, you cannot watch for ACL changes. it is one of the API/implementation simplifications we did since we didn't have a good use case for it. it does seem a little bit weird. we are following file system semantics here. i guess for ultimate security only clients with admin permission would be able to see an ACL. ben On 02/22/2010 08:00 AM, Mark Masse wrote: Hi, Does anyone know if there's a way to get a Watcher notification when a znode's ACL changes?

Znode ACL watcher?
Hi, Does anyone know if there's a way to get a Watcher notification when a znode's ACL changes? I also wanted to ask if it seems weird that you can "read" a znode's ACL even if you don't have permissions to read the data. Thanks, -- Mark Masse http://www.massedynamic.org
