Nate Cole commented on AMBARI-17285:
------------------------------------
I think that we should probably add a directive that will allow preserving of
stack-defined repos when using VDF. As an example
HDP/2.5 defines two repos, name/id'ed by HDP/HDP-2.5 and
HDP-UTILS/HDP-UTILS-1.1.0.20.
This directive would be used with the following logic: If passing the
directive (to be named) as {{true}}, check if there are any repos that do NOT
match the ids within the VDF, and use them for the repo version. Therefore:
||Directive||Stack||VDF||Repo Version||
|false (default)|HDP\\HDP-UTILS|HDP\\HDP-UTILS|HDP\\HDP-UTILS|
|true|HDP \\ HDP-UTILS\\SOME-REPO|HDP \\ HDP-UTILS|HDP \\ HDP-UTILS\\SOME-REPO|
We can default to either {{true}} or {{false}}, I'm not too picky on that
point. Thoughts welcome.

> URL: https://issues.apache.org/jira/browse/AMBARI-17285
> Project: Ambari
> Issue Type: Bug
> Reporter: Alexander Denissov
> Assignee: Nate Cole
> Priority: Critical
> Fix For: 2.4.0
>
>
> Ambari 2.4 introduced Version Definition Files that break the functionality
> of adding a custom service repo, since custom services do not have an entry
> in the public VDF.
> In the case of HAWQ, the plugin is installed on Ambari host and it adds the
> new repo information to the repoinfo.xml of all available stacks on the file
> system. Once Ambari cluster creation wizard queries the latest repo info from
> the public URLs, it will get the info for all stack repos, but not the custom
> ones.
> So, the logic should be:
> 1. Use default repoinfo (from file system) as the base
> 2. Query public VDF, if available
> 3. For each entry in public VDF overwrite values in the default repoinfo
> 4. Entries in default repoinfo that do not have corresponding entries in VDF
> should stay intact
> This way custom services can be added via file edit and the latest
> information can still be retrieved and applied for the standard stack.
