Hi Mahadev, Once I stop all the services I am able to successfully recreate the services. Also pre installing the rpms also speed my deployment.
Can you tell me the JIRAs for the management API's We do have few doubts on the APIs exposed.

Also if you planning to automate this, you might want to try out the management API's (please beware that these are not stable and will only be published for integration with 1.3.0): curl -u admin:admin -i -X PUT -d '{"ServiceInfo": {"state": "INSTALLED"}}' http://<ambari-server>:8080/api/v1/clusters/<clustername>/services For the rpm's you can probably create a list using rpm -qa diff after and before the install. You should be able to pre install them to speed things up. thanks mahadev From: Modeel, Subin Sent: Friday, March 08, 2013 12:42 PM To: '[email protected]' Subject: Create a new cluster on the same hardware Hi, I have used Ambari to create a hadoop cluster with all services on my 7 node cluster. Suppose now I want to recreate the cluster. I have done a ambari-reset .But I believe the services are still running on the nodes. What is the safe way to make sure I have stopped all the services running on all nodes. I also want to save my time every time I create cluster on the 7 nodes. IS there way I can pre- install all the rpm on all the nodes. If so what are all the rpms I can pre install. Thanks Subin11
