Concise and neat!
It would be great if you can add some comments on 
{code}
    try {
            children = zk.getChildren(path, watch, stat);
        }
        catch (KeeperException.NoNodeException e) {
            err.println("Node does not exist: " + e.getPath());
            return allChildren;
        }
{code}
otw lgtm.

> When troubleshooting applications where znodes can be multiple levels deep  
> (eg. HBase replication), it is handy to see all child znodes recursively 
> rather than run an ls for each node manually.
> So I propose adding an option to the "ls" command (-r) which will list all 
> child nodes under a given znode.
