------------------------------------

             Summary: There needs to be a repository of services that exists 
outside the scope of any vendor-specific stack. Such services should be 
available to vendor-specific stacks via service inheritance.
                 Key: AMBARI-7201
                 URL: https://issues.apache.org/jira/browse/AMBARI-7201
             Project: Ambari
          Issue Type: Epic
          Components: stacks
    Affects Versions: 2.0.0
            Reporter: Robert Levas


*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.
