> We should support YARN security for new TimelineService.
> Basically, there should be security token exchange between AM, NMs and 
> app-collectors to prevent anyone who knows the service address of 
> app-collector can post faked/unwanted information. Also, there should be 
> tokens exchange between app-collector/RMTimelineCollector and backend storage 
> (HBase, Phoenix, etc.) that enabling security.
