Description
We missed this during our full dev deployment because we use blueprints, which seems to bypass the service_advisor mechanism in Ambari.
If you uninstall Metron and attempt to reinstall the service (or do any fresh install for that matter), the service recommendations will fail due to missing hostnames in the services list. The following stack traces appear in the Ambari server logs.
Error occured in stack advisor.

The recommended hosts are not something we own, afaik, so it's highly likely that this is a bug in Ambari.
