your command should be similar to like below:

curl -u admin:admin -i -H "X-Requested-By: ambari" -X PUT -d '{"HostRoles" : {"state" : "INSTALLED"}}' http://localhost:8080/api/v1/clusters/<Cluster Name>/hosts/<hostName where you have any issue>/host_components/< MAPREDUCE2_CLIENT>

If you click on "Installed" you should see an option to "Refresh Configs". Can you check if clicking on it addresses your issue?

When I clicked on refresh configs, it restarted all the clients. Still issue persists.

root cause for your issue is : client in INSTALL_FAILED state

Solution: Provided API call to set it in INSTALLED state
