If you want to get the HA Status (Active/Standby) for ResourceManager then you can make the following call:

# curl -s -u admin:admin -H "X-Requested-By: ambari" -X GET "h ttp://$AMBARI_FQDN:8080/api/v1/clusters/$CLUSTER_NAME/host_components?HostRoles/component_name=RESOURCEMANAGER&HostRoles/ha_state.in(ACTIVE,STANDBY)"

If you just want to know that which host the ResourceManager is in Active State then:

# curl -s -u admin:admin -H "X-Requested-By: ambari" -X GET "h ttp://$AMBARI_FQDN:8080/api/v1/clusters/$CLUSTER_NAME/host_components?HostRoles/component_name=RESOURCEMANAGER&HostRoles/ha_state=ACTIVE"

.

Dear Jay - we try this API but no any status from API,
