> Ambari Server has "sensible" defaults for many of the configurations in {{ambari.properties}}.
They may work for 5-, 10-, 50-, or even 100-host clusters. However, they _must_ be properly
tuned in any situation which has a large, production-level topology. 
> There is currently sparse to no documentation on many of these properties. For every
property, we need to consider:
> - The context in which different cluster deployments could be affected by it
> -- Cluster Size
> -- Cluster History
> -- Concurrent Users
> - Provide recommendations that are grouped logically, such as (for example)
> -- Multiple Concurrent Users
> -- 50 to 100 Hosts
> -- Ambari Server Hardware
