Fix For: ambari-server, 2.7.3
now, we use Ambari to manage more than 3000 hosts, 20+ Components. we found
that, the interface
"[http://ip:port/api/v1/clusters/TL0/services?fields=ServiceInfo/state,ServiceInfo/maintenance_state,ServiceInfo/desired_repository_version_id,components/ServiceComponentInfo/component_name&minimal_response=true&_=1572316944944|http://10.128.142.193:8080/api/v1/clusters/TL0/services?fields=ServiceInfo/state,ServiceInfo/maintenance_state,ServiceInfo/desired_repository_version_id,components/ServiceComponentInfo/component_name&minimal_response=true&_=1572316944944]";
is too slow, it will cost about 1.5mins every request.
This interface is requested every time the UI is refreshed. For example, after
modifying the configuration, exiting the add service interface, etc., this
interface will be requested.
the installed Ambari version is release-2.7.3
