> Currently stack API exposes component level dependencies which does not roll
> up to service level dependency is required for restricting user to install a
> service that cannot work in the absence of a dependent service.
> Currently there is a hard-coded map in the ambari-web code for service
> dependency which restricts this validation functionality to only known
> services of HDP stack.  
> service dependency map:
