-------------------------------------
Summary: Add predicate objects for checking empty resource
category & category count
Key: AMBARI-1270
URL: https://issues.apache.org/jira/browse/AMBARI-1270
Project: Ambari
Issue Type: Bug
Reporter: Tom Beerbower
Assignee: Tom Beerbower
We need to be able to check through the API to see if a property category
contains any properties.
For example, if we want to check to see if configurations have been overridden
then we can look at the ServiceInfo/desired_configs of a component resource. If
desired_configs is empty then there are no config overrides.
Through the API, we can examine the ServiceInfo/desired_configs property but we
have no way to write a predicate that would allow us to query for components
that contain config overrides.
In order to allow for such a query, we need the underlying predicate objects.
