Sumit Mohanty commented on AMBARI-3606:
---------------------------------------
_Sorry for the delay. Let's open a separate JIRA for the ones needed to be
incorporated._
* What happens when a host gets deleted? Does the ref from CG to host also get
deleted? Is there a unit test for that?
* (Minor nit) Javadoc missing for new methods on AmbariManagementController
*
ambari-server/src/main/java/org/apache/ambari/server/controller/internal/ConfigGroupResourceProvider.java
** Set<ConfigGroupResponse> getConfigGroups () - is it possible to have a
request with more than one predicate, e.g. groupName and hostName?
* These files can be reverted (unused imports or fields)
**
ambari-server/src/main/java/org/apache/ambari/server/controller/internal/RequestStatusImpl.java
**
ambari-server/src/main/java/org/apache/ambari/server/controller/internal/ResourceImpl.java
** ambari-server/src/main/java/org/apache/ambari/server/state/Clusters.java
**
ambari-server/src/main/java/org/apache/ambari/server/state/cluster/ClustersImpl.java
* ambari-server/src/main/resources/Ambari-DDL-Postgres-REMOTE-CREATE.sql'
** Should not there be a corresponding change to Ambari-DDL-Postgres-CREATE.sql
> Add ConfigGroup resource provider to support API calls

> Configuration group or Config group (CG) is type of Ambari resource that
> supports grouping of configuration resources and host resources for a
> service, service component or host component. Host is identified using the
> registered hostname of the host and the configuration resource is identified
> by the type and tag. The CG will have a unique name and CRUD operations will
> be supported on a CG using the unique group name.
> *GET*
> Get a collections of Config group resources for a service. Query example does
> not show the expanded view.
> *POST*
> Create a Config group, list of hosts or configurations is not a required
> field. If the configuration object contains properties, the Ambari server
> will create a new configuration resource with the new type and tag or throw
> appropriate exception. Properties provides only the key value pairs which
> have been changed. These will be applied on the cluster level configurations.
> *PUT*
> Update a config group definition, this API call would expect the object to be
> sent in its entirety and will atomically update the resource. PUT call can
> accept properties as well.
> *DELETE*
> Delete a config group resource, this will not do a cascade delete of any
> other resource.
