Newton Alex commented on AMBARI-7175:
-------------------------------------
Sorry I might not be aware of the complete existing stack inheritance
implementation. From the current proposal,
I'm guessing it will not be possible to have information distributed between
the base and the derived files.
If some one plans to inherit, will they have to copy all the information from
the base file into the derived one as the entire file will get overwritten?
Please correct me if I'm wrong.

> Enable stacks to inherit individual services with the same stack or across
> stacks.
> When creating a new version of a service definition, unchanged details and
> scripts need to be copied from the previous version to the new version. Any
> changes made to the resources that have been copied need to be propagated to
> them. This can be tedious and time consuming as well as lead to user error
> while copying the changes. Currently, one version of a stack can extend
> another version of the same stack and will inherit everything in the stack
> including potentially unwanted content. This work is to allow single
> services to be inherited/extended as opposed to the entire stack.
