Once accepted, did it start a job in the Ambari Ops? Please check for any errors in the Ambari Opts listing for this job. Also tail ambari-server.log for this period and observe if any error is reported related to this curl command.

It got worked for me with the following command :.

curl -u admin:password -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo":{"context":"Stop NODEMANAGER"}, "Body":{"HostRoles": {"state": "INSTALLED"}}}' http://viceroy10:8080/api/v1/clusters/et_cluster/hosts/$hostname/host_components/NODEMANAGER

I dont know what is the difference between both commands?
