Aaron Crow commented on ZOOKEEPER-679:

Hi Chris, my apologies, I haven't had much time to continue with this patch. I 
kind of got held up by the combination of limited time, and apparently being 
required to engineer a standalone build for the patch. 

This is actually my first significant contribution, so I'm feeling a little 
lost at this point. Is it kosher to move patches out of zk contrib and into 
independent repos? And what would make it easer to collaborate on in github vs. 
the main zk project?

Many thanks for your interest and time...

> Following up on my conversations with Patrick and Mahadev 
> (http://n2.nabble.com/Might-I-contribute-a-Node-design-for-the-Java-API-td4567695.html#a4567695).
> This patch includes the implementation as well as unit tests. The first unit 
> test gives a simple high level demo of using the node API.
> The current implementation is simple and is only what I need withe current 
> project I am working on. However, I am very open to any and all suggestions 
> for improvement.
> This is a proposal to support a simplified node (or File) like API into a 
> Zookeeper tree, by wrapping the Zookeeper Java client. It is similar to 
> Java's File API design.
> Although, I'm trying to make it easier in a few spots. For example, deleting 
> a Node recursively is done by default. I also lean toward resolving 
> Exceptions "under the hood" when it seems appropriate. For example, if you 
> ask a Node if it exists, and its parent doesn't even exist, you just get a 
> false back (rather than a nasty Exception).
> As for watches and ephemeral nodes, my current work does not need these 
> things so I currently have no handling of them. But if potential users of  
> the "Node a.k.a. File" design want these things, I'd be open to supporting 
> them as reasonable.
