I'd like to file a pr about pass path info if meaningful when {{KeeperException}} s threw in {{DataTree}}.

Maybe in recent days. I'll appreciate it if you or others can review it :-)

> Currently, if ZooKeeper delete a znode that does not exist. It throws a {{KeeperException.NoNodeException}} without path message. It causes difficulty when user debug with ZooKeeper. For example,
> Assume we try to do a transaction(with Curator encapsulation)
> {code:java}
> client.inTransaction()
>    .check().forPath(path1).and()
>    .delete().forPath(path2).and()
>    .commit()
> {code}
> if the statement throw an exception {{KeeperException.NoNodeException}} without path information, we can hardly know that it failed at {{check}} or {{delete}}.
> Thus I propose throws KeeperException with path in DataTree operations. We can achieve this without burden.
