I needed to somehow find the hosts running each service and I knew it was
contained in this `clusterHostInfo` configuration. But it was really difficult
to uncover what values Ambari keeps in this `clusterHostInfo` configuration. I
have not been able to find any documentation on this.
I actually had to add some debug statement to a live instance of Ambari to
find out what values are stored here and how they are named. Fun, fun.
For the record, here is what is stored in `clusterHostInfo` when spinning
up the current state of Full Dev.
