> Enable Stack Service Inheritence
> --------------------------------
>
> Key: AMBARI-7175
> URL: https://issues.apache.org/jira/browse/AMBARI-7175
> Project: Ambari
> Issue Type: New Feature
> Components: stacks
> Reporter: John Speidel
> Assignee: John Speidel
> Labels: stack
> Attachments: StackServiceDefinitionInheritanceTechnicalDocument.docx
>
>
> 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.
