> ZookeeperClientService may hang at startup and then cannot be stopped

> Project: Apache Twill
> Issue Type: Bug
> Reporter: Andreas Neumann
>
> 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.
