Description

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.
