Description

We have a situation where service components that have been installed and previously working have disappeared from the API response.
/api/v1/clusters/cluster_name/services/YARN/components does NOT return NODEMANAGER
/api/v1/clusters/cluster_name/services/STORM/components does NOT return SUPERVISOR
Note that Ambari Server shows an ERROR when loading these service components, but the server continues the startup sequence.
Ambari Web is even usable and you can login, but the YARN and STORM service summary panels show invalid info (and other operations fail, since the server thinks these service components don't even exist).

Ambari DB consistency should be check during ambari-server start
