Configuration (Ambari Server 3.0.0.0-SNAPSHOT API)

java.lang.Object
- org.apache.ambari.server.configuration.Configuration

```
public class Configuration
extends Object
```
The Configuration class is used to read from the {{ambari.properties}} file and manage/expose the configuration properties. Each property is wrapped in a Configuration.ConfigurationProperty type, allowing the coupling of the key, default value, and type.
The main(String[]) method can be invoked to produce Markdown of all of the properties, along with their default values and descriptions. This should be done for every release so that the documentation of the configuration properties can be kept current. The index_template.md file is used to generate the markdown.
The markdown can also be generated by running the site phase in maven or by running the exec:java goal directly:
```
 mvn site
 mvn exec:java
 mvn exec:java@configuration-markdown (on maven 3.3.1 and later)
 
```
