Michael Miklavcic commented on AMBARI-25375:
--------------------------------------------
I printed out the list of services and components and then grepped for empty
hostnames. These are the components based on searching the attached
ambari-2.7-hostnames.txt file.
{code:java}
grep -A1 'hostnames'\'': \[\]' ambari-2.7-hostnames.txt

> Apache Metron currently leverages the MPack feature for installing as a
> service in Ambari. In 2.7.3.0 the stack advisor does not return hostnames for
> all services and components. We've attempted a workaround in our
> ServiceAdvisor, however testing in a multi-node cluster still results in
> failures.
