Can we manage client configuration through ambari too? For an example, I want to modify parameters in hst-agent.ini in 15 servers, how can I do it? Do I need to do manually on the server? Or can we do through ambari?
"hst-agent.ini" is usually have almost the same content on all the hosts. It is not managed via Ambari UI (ambari does not provide option to manage/edit this hst-agent.ini) from UI. So changes in this file needs to be done manually. Easiest will be to make the config changes and then push it to other hosts.
