I would take a look at the Apache Ambari API reference. I think that this link might be of use: https://github.com/apache/ambari/blob/trunk/ambari... For a list of all configurations to the API you could make a call similar to the following GET /api/v1/clusters/cluster/configurations Then if you wanted to get all of the configuration versions for Hive you could make the call to GET /api/v1/clusters/cluster/configurations?type=hive-site And from that list if you picked one of the versions you would make a call like: /api/v1/clusters/Sandbox/configurations?type=hive-site&tag=version1447446748723 The response would look something like: {
"href" : "http://localhost:8080/api/v1/clusters/Sandbox/configurations?type=hive-site&tag=version1447446748723",
"items" : [
