>                 URL: https://issues.apache.org/jira/browse/AMBARI-5599
>             Project: Ambari
>          Issue Type: Bug
>    Affects Versions: 1.5.0, 1.5.1
>            Reporter: Gordon Hamilton
>            Assignee: Nate Cole

> In 1.4.x, I was able to switch between configurations using the following curl command:
> {code}
> curl -u <user>:<password> -X PUT -H "X-Requested-By: ml" http://<address>:8080/api/v1/cluster/AMCluster1 -d '{"Clusters":{"desired_config":{"type":"hdfs-site","tag":"version1"}}}'
> {code}
> However, in 1.5.x, this doesn't appear to work anymore even though documentation suggests it should. https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/configuration.md
> I now see the following error:
> {code}
> {
>   "status" : 500,
>   "message" : "org.apache.ambari.server.controller.spi.SystemException: An internal system exception occurred: Configuration with tag 'version1' exists for 'hdfs-site'"
> }
> {code}
> The work-around for this is to perform a GET on previous configuration that is required and create it as a new configuration, setting the desired_config at the same time.
