What version of Ambari are you using? Using version 1.2.5.17, you can use the following to delete the cluster.
curl u username:password X DELETE http://<ambari server>:8080/api/v1/clusters/<cluster <http://localhost:8080/api/v1/clusters/<cluster> name> If you are trying get your host(s) to a clean state and reinstall Ambari then https://cwiki.apache.org/confluence/display/AMBARI/Cleaning+up+machines+for+ Ambari+and+Stack provides some guideline around cleaning up the host(s). -Sumit From: Christian Smith <[email protected]> Reply-To: <[email protected]> Date: Tuesday, September 3, 2013 2:04 PM To: "[email protected]" <[email protected]> Subject: Simplest way to delete cluster via API? Hi, I'm trying to delete a configured cluster with all services and components via the API with no success. I keep getting errors like: org.apache.ambari.server.AmbariException: Invalid transition for service, clusterName=hadoop1, clusterId=2, serviceName=HDFS, currentDesiredState=INSTALLED, newDesiredState=UNINSTALLED I have two questions, 1) What's the simplest option to delete a cluster and all its config (e.g. -force option) via the API? I just want the config removed from Ambari as I will be destroying the cluster VMs. 2) What are the steps to gracefully delete a cluster and all services/components via the API?
