---------------------------------
Summary: Stack/Service/Component/Configurations API call returns
invalid JSON response in some cases
Key: AMBARI-8124
URL: https://issues.apache.org/jira/browse/AMBARI-8124
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 1.7.0
Reporter: Greg Hill
The HBASE 'content' configurations item returns two JSON data structures
separated by a space. This is not a valid response in a JSON API. The response
needs to wrap the items in a list structure. Here is the call and response
from a default ambari install on 1.7.0:
