----------------------------------------

             Summary: Create Documentation Around All Options In ambari.properties
                 Key: AMBARI-18089
                 URL: https://issues.apache.org/jira/browse/AMBARI-18089
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.4.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Critical
             Fix For: 2.5.0


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
