> Key: ZOOKEEPER-1899
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1899
> Project: ZooKeeper
> Issue Type: Bug
> Affects Versions: 3.4.5
> Environment: Centos 6, Claudera Hadoop 5
> Reporter: Srinath Mantripragada
>
> When running a zookeeper-cli, any error or logging information should go to STDERR and the result(s) of the command to STDOUT. For example, let's take the unix 'ls' command:
> Unix, STDERR is redirected to '/dev/null' and no results are shown:
> {code}
> $ ls /aa 2> /dev/null
> {code}
> zookeeper-cli, everything goes to STDOUT where only the last line should:
> {code}
> zookeeper-client ls / 2> /dev/null
> Connecting to localhost:2181
