-- An optional configuration specification to be used when provisioning
-- cluster instances, which can include configurations for applications and
-- software bundled with Amazon EMR. 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. For more
-- information, see
