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
