Robert Levas updated AMBARI-7201:
---------------------------------
Description:
*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.
See [^CommonStackServicesTechnicalDocument.pdf] for more information.
