Review request for Ambari, Alejandro Fernandez and Sid Wagle.
Bugs: AMBARI-10405
https://issues.apache.org/jira/browse/AMBARI-10405
Repository: ambari
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
