>  Dear Openstack Developers,
>
>  My name is Yanchao Liang. I am a software engineer in eBay, working on
> Hadoop as a Service on top of Openstack cloud.
>
>  Right now we are using Sahara, Juno version. We want to stay current and
> introduce global template into sahara.
>
>  In order to simplify the cluster creation process for user, we would
> like to create some cluster templates available for all users. User can
> just go to the horizon webUI, select one of the pre-popluated templates and
> create a hadoop cluster, in just a few clicks.
>
>  Here is how I would implement this feature:
>
>    - In the database, Create a new column in “cluster_templates" table
>    called “is_global”, which is a boolean value indicating whether the
>    template is available for all users or not.
>    - When user getting the cluster template from database,  add another
>    function similar to “cluster_template_get”, which query the database for
>    global templates.
>    - When creating cluster, put the user’s tenant id in
>    the “merged_values” config variable, instead of the tenant id from cluster
>    template.
>    - Use an admin account create and manage global cluster templates
>
> Since I don’t know the code base as well as you do, what do you think
> about the global template idea? How would you implement this new feature?
>
>  We would like to contribute this feature back to the Openstack
> community. Any feedback would be greatly appreciated. Thank you.

>  Best,
