### Component-level configuration properties
Component-level service AM configuration properties can be specified either in the cluster `yarn-site.xml` at the global level (effectively overriding the default values system-wide), specified per service in the `properties` field of the `Configuration` object, or specified per component in the `properties` field of the component's `Configuration` object.
