Robert Levas updated AMBARI-7201:

> *Problem*
> The current implementation of the Ambari stack does not allow for a common set of services to be defined and reused in vendor-specific stack definitions. Therefore in order for the same service to be made available to different stacks, it’s definition must be copied or inherited from stack to stack.  
> *Solution*
> There needs to be a repository of services that exist outside the scope of any vendor-specific stack, but are accessible to vendor-specific stacks via service inheritance. This set of services should be known as common services and are to be maintained by the community to ensure that changes do not break vendor-specific services that inherit from them.
