Robert Levas commented on AMBARI-7201:
--------------------------------------
[~nalex], Thanks!
bq. 1) What would be the common service definitions tested against? Are we
looking at Bigtop rpms?
I am not too sure. I was hoping the community will join together and ensure
that we have a good place for that.
bq. 2) Minor fix:
I appreciate the fix for my documentation issue. I will correct it and upload a
new PDF.
bq. 3) I have some comments on the versioning of the service definitions. We
are dealing with two variables here:
I really like your ideas on versioning... thanks for pointing out the lack of
details on this in the specification. You obviously put a lot of thought into
this and I think that both schemas are great. My need to be explicit favors
flavor II... even if it is a bit wordy. I will add one of these conventions to
the document, but I want to see if anyone chimes in against or for either of
those scenarios.
> Common Services
> ---------------
>
> Key: AMBARI-7201
> URL: https://issues.apache.org/jira/browse/AMBARI-7201
> Project: Ambari
> Issue Type: Epic
> Components: stacks
> Affects Versions: 2.0.0
> Reporter: Robert Levas
> Labels: common-services, service, stack
> Attachments: CommonStackServicesTechnicalDocument.pdf
>
> Original Estimate: 504h
> Remaining Estimate: 504h
>
> *Problem*
> The current implementation of the Ambari stack does not allow for a common
> set of services to be defined and reused in vendor-specific stack
> definitions. Therefore in order for the same service to be made available to
> different stacks, it’s definition must be copied or inherited from stack to
> stack.
> *Solution*
> There needs to be a repository of services that exist outside the scope of
> any vendor-specific stack, but are accessible to vendor-specific stacks via
> service inheritance. This set of services should be known as common services
> and are to be maintained by the community to ensure that changes do not break
> vendor-specific services that inherit from them.
> See [^CommonStackServicesTechnicalDocument.pdf] for more information.
