How to restart/refresh client config on all the hosts using Ambari API

shyamshaw — Mon, 16 Sep 2019 08:40:26 GMT

Below article shows how to restart clients on Specific host.

https://cwiki.apache.org/confluence/display/AMBARI/Restarting+host+components+via+the+API

Is there any way we can perform the same on all the hosts in the cluster at one time.

Thank you in advance.
