Nate Cole commented on AMBARI-3548:
-----------------------------------
* The ability to provide repository information exists with the stack, and
several repos may be used per OS. I hesitate on putting repos at the service
layer. In addition, repos at the service layer conflicts with custom
repo-base-url functionality.
* The Spec indicates artifacts to the agent ({{script}}, {{templates}}) go in
their own {{PACKAGE}} directory. This would make it easy to bundle up into a
tar and send down. (We can still read the metainfo from Ambari for the
commands/actions available).
* I think JSON vs XML is a good question. We can pick either, but should be
consistent. The question is - which format will authors have an easier time
with?
* Patch name says AMBARI-2036 - is that for this issue?
> Changes to stacks definitions to allow custom services support (needed by an
> ambari-agent)

> Project: Ambari
> Issue Type: Bug
> Components: controller
> Affects Versions: 1.5.0
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Fix For: 1.5.0
>
> Attachments: AMBARI-2036-preview.patch, hbase_new_metainfo.json,

>
> Stack definitions for custom services should contain fields:
> - service metadata
> -- list of repositories
> - component metadata should contain fields:
> -- scriptType (possible values: "python", "puppet")
> -- taskTimeout (per-component value)
> Except metadata files, custom service directory should contain:
> - script directory that contains separate python files for components (e.g.
> namenode.py, datanode.py etc.) and service.py file.
> - a separate directory for templates
> Patch is so large because I've created a separate stack dir with modified
> HBase metadata.
