Is this JIRA still and its sub-tasks still relevant?

>    Affects Versions: 1.7.0

> We'd like to retrieve metadata information (most of them are already persisted) through
the API. We have open sourced a project called Periscope
which brings SLA policy based autoscaling for Hadoop clusters installed with Ambari, and when
up and downscaling clusters we need to know certain metadata information listed below - these
features we have implemented in Periscope but would like to add in Ambari API, REST client
and shell:
> 1. Ability to know the host-hostgroup relationship - from both directions
> 2. Ability to know the services/components-host relationship - from both directions
> 3. Ability to know the blueprint-cluster(s) relationship
> 4. Once Slider is supported, keep and retrieve the Slider apps related metadata
