Sumit Mohanty commented on AMBARI-3548:
---------------------------------------

Regarding the patch - let's agree on the specification structure. I think after that the patch
will need some changing.

Otherwise, the changes look fine.

> 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.
