we try by the following API , but API not return any output

curl -sH "X-Requested-By: ambari" -u admin:admin -H "X-Requested-By: ambari" -X GET http://master:8080/api/v1/clusters//services/HDFS

You are hitting with wrong values.

Find below example:

curl -u admin:password "http://{hostname}:8080/api/v1/clusters/{cluster _name}/host_components?HostRoles/"

@mike_bronson7 Use the following API to find out the node & state of the active/standby

# curl -u <User name>:<Password> -H 'X-Requested-By: ambari' -X GET 'http://test1:8080/api/v1/clusters/c186/host_components?HostRoles/componentname=NAMENODE&metrics/dfs/FSNamesystem/HAState=active' # curl -u <User name>:<Password> -H 'X-Requested-By: ambari' -X GET 'http://test1:8080/api/v1/clusters/c186/host_components?HostRoles/componentname=NAMENODE&metrics/dfs/FSNamesystem/HAState=standby”

fix: `componentname` should be `component_name`
