Tim Thorpe commented on AMBARI-15538:
-------------------------------------
Will the repos folder be linked to all services? I guess this is to reduce
duplication? Is this going to be specific to custom services? What about
extensions? Would I need to include the repos directory under all services in
the extension or I just include EXT/1.0/repos/repoinfo.xml and it would
automatically get associated with all services in that extension?
Couldn't the repos just be included directly under the service folder? Could I
have mpacks/custom-services/8.0.0/SERVICEA/repos/repoinfo.xml
If so will there be anything to prevent an mpack from doing both? Such that if
a service has its own repos folder that it would be an error to either have one
at the custom services level or potentially it just wouldn't link the other one.
Will services under the stack be allowed to specify their own repos? Either
those directly in any of the HDP stack versions, or in an mpack?

>
> The approach for custom-services to specify their own repo location will be
> to provide a {{/repos/repoinfo.xml}} inside the stack-version they will be
> in. This repo file will be loaded by Ambari during startup into the
> {{/api/v1/stacks/HDP/versions/2.4/repository_versions}} repos. *Service repo
> files have a restriction that their (repo-name, base-url) locations should be
> unique and not conflict*. When conflicts do occur, they will not be loaded
> into the stacks model.
> Now the management-pack will provide such repos/ folder in
> {{mpacks/custom-services/8.0.0/repos}} which will be linked into the stacks/
> folder.
> {{ambari/ambari-server/src/main/resources/stacks/HDP/2.3/services/SERVICE_NAME/repos
> -> mpacks/custom-services/8.0.0/repos}}
