# AWS::EMRServerless::Application ConfigurationObject
<a name="aws-properties-emrserverless-application-configurationobject"></a>

A configuration specification to be used when provisioning an application. A configuration consists of a classification, properties, and optional nested configurations. A classification refers to an application-specific configuration file. Properties are the settings you want to change in that file.

  "[Configurations](#cfn-emrserverless-application-configurationobject-configurations)" : [ ConfigurationObject, ... ],
  "[Properties](#cfn-emrserverless-application-configurationobject-properties)" : {Key: Value, ...}
}
```

### YAML
<a name="aws-properties-emrserverless-application-configurationobject-syntax.yaml"></a>
