Are we able to stop ambari agents without logging into each and every host? Can we do make it possible from ambari server?

@Ram D. If you have passwordless SSH set up from the Ambari Server to all the hosts with Ambari Agents, you can use a distributed shell, such as pdsh, to issue the command to your hosts and stop the Ambari Agents. Doing so from the Ambari Server console is not an option and I do not believe it will be based on the architecture type that Ambari uses.

Mobaxterm, pdsh, ansible, chef, saltstack any of these tools can execute in parallel across your nodes.
