>             Project: Apache Twill
>          Issue Type: Bug
>          Components: zookeeper
>    Affects Versions: 0.2.0-incubating, 0.1.0-incubating, 0.3.0-incubating, 
> 0.5.0-incubating, 0.4.1-incubating
>            Reporter: Andreas Neumann
>            Assignee: Terence Yim
>             Fix For: 0.6.0-incubating
>
>
> If the Zookeeper quorum is configured incorrectly, then the ZK client service 
> will wait for ZK to come up, and it won't start until it can connect to ZK. 
> While it is in this state, it can now not be stopped, because stop() will 
> wait for the state to become RUNNING before it does anything. 
> There should be a way to stop a service that hangs at startup.
