Sumit Mohanty commented on AMBARI-3548:
---------------------------------------
To [[email protected]]'s comments:
We will definitely have the repo information at the top level. The idea for
keeping it at service level is to allow addition of services that are not
released as part of HDP. So we need a room for repo URL at the level of
services. For the next 4-5 services we are adding we will not need the repo url
as they will all, most likely, be part of HDP. Anyway, the custom-url feature
will only work if all services are part of the same repo - in which case we do
not need to specify repo url at the service spec.
I am OK with either creating PACKAGE folder or packing the whole "HBASE" folder
including configuration, metainfo, etc. The later is probably little wasteful.

> 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.
