@Huahua Wei Please login into the Grafana as admin, then go to Datasources and test connection. If that fails, instead of Ambari metrics collector hostname, try adding IP and see if you face the same issue.

If nodemanager.recovery.enabled is set to true, please set it to false and try starting the nodemanager. This should get you unblocked.
