[~djp]

I am not sure if restart is an expectation at the beginning. But theoretically, 
any services should be restartable. However, just double checked with other 
services, like: NodeManager, ResourceManager, etc., it seems like all these 
services are implemented as one time only service. So I am fine with keeping 
things like this to conform the same pattern with other services. I will file 
another separated JIRA to discuss restartable issue unless someone tells me a 
solid reason on this.
