    Description

      While TwillRunnerService.startAndWait() requests application/controller state from Zookeeper, there may be a delay in retrieving this state. This can cause subsequent lookup() calls to return null even if there is a Twill application running.

      While this can be prevented by adding a one second sleep after startAndWait() is called, it would be better if startAndWait() was modifed to not return until all state has been retrieved from Zookeeper.
