>                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2359
>             Project: ZooKeeper
>          Issue Type: Improvement
>          Components: java client
>    Affects Versions: 3.5.1

>         Attachments: ZOOKEEPER-2359.patch
> ClientCnxn.java logs errors during watcher removal:
> LOG.error("Failed to find watcher!", nwe);
> LOG.error("Exception when removing watcher", ke);
> An error code/exception is generated so the logs are noisy and unnecessary. If the client
handles the error there's still a log message. This is different than other APIs. These logs
should be removed.
