This API will get you status of all components on all hosts in your cluster

curl -u {ambari_username}:{ambari_password} -H "X-Requested-By:ambari" -i GET http://localhost:8080/api/v1/clusters/cl1/components?fields=host_components/HostRoles/state

And if you need to find the status of individual component e.g for datanode;

curl -u {ambari_username}:{ambari_password} -H "X-Requested-By:ambari" -i GET http://localhost:8080/api/v1/clusters/cl1/components/DATANODE?fields=host_components/HostRoles/state

Hope this helps!
