Whenever I tried to assign more than 3-5 hosts to a config group, ambari server would timed out with this error "14:57:40,393 ERROR [qtp2032601831-333] BaseProvider:143 - Timed out waiting for metrics." then stopped responding until I restart the server. This makes it impossible to assign hosts to different config groups.
Any idea on how to resolve this?
Ambari Version1.7.0
HDP 2.2.4
