--------------------------------------------------------------
I'd like to file a pr about pass path info if meaningful when
{{KeeperException}}s thrown in {{DataTree}}.
Maybe in recent days. I'll appreciate it if you or others can review it :)

> Throw KeeperException with path in DataTree operations

> Key: ZOOKEEPER-3289
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3289
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.5.4, 3.4.13
> Reporter: TisonKun
> Priority: Major
> Fix For: 3.5.5, 3.4.14

>
> 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.
