> Problem in this place when waiting for JHS to be started
> {code}
> new Thread() {
> public void run() {
> historyServer.start();
> };
> }.start();
> while (historyServer.getServiceState() == STATE.INITED) {
> LOG.info("Waiting for HistoryServer to start...");
> Thread.sleep(1500);
> }
> {code}
> The service state is updated before the service is actually started. See
> AbstractServic#start. So it's possible that when the while loop breaks, the
> service is not yet started.
