> Druid start component via ambari doesn't wait to check if the component is successfully
started.
> Any component start for Druid service will just  execute the start command and comes
out with exit status 0. It will not further check if the process is running, or any port if
its listening.
> say for example Druid Coordinator
> {code}

> Command completed successfully!

> The start command via Ambari-UI shows as passed on Ambari-ops even if the component fails
to start. this gives false impression to check the service.
