Tim Thorpe commented on AMBARI-15538:
-------------------------------------

I will try to look at this tomorrow.  Sorry I've been busy with customer issues 
today.  [~jluniya] do you mean more than one version of the same service in the 
same extension version?  For example in EXT/1.0 containing 2 different 
MY_SERVICE versions?  If so, this won't be supported until the stack is able to 
do the same thing.  If you mean EXT/1.0/services/MY_SERVICE (version 0.1) and 
EXT/1.1/services/MY_SERVICE (version 0.2) then this is already supported.

> Support service-specific repo for add-on services

> 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}}
