> For hosts with dual network cards and configured with two FQDN, it's possible to manually
config NN HA with alternative FQDN than the ones recorded in the Ambari database. This caused
an issue for EU/RU when upon kicking off the upgrade via UI, the UI immediately posts the
following error:
> "An internal system exception occurred: Request specifies host XXXXX but it is not a
valid host based on the target service=null and component=null"
