Subject [jira] [Created] (ZOOKEEPER-3289) Throw KeeperException with path in DataTree operations
Date Mon, 25 Feb 2019 05:20:00 GMT
TisonKun created ZOOKEEPER-3289:
-----------------------------------

             Summary: 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: 3.4.13, 3.5.4
            Reporter: TisonKun
             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.
