Documentation

data Configuration

Amazon EMR releases 4.x or later.

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 Configuring Applications.

See: newConfiguration smart constructor.

Constructors

• classification :: Maybe Text

newConfiguration :: Configuration

Create a value of Configuration with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:classification:Configuration', configuration_classification - The classification within a configuration.

$sel:configurations:Configuration', configuration_configurations - A list of additional configurations to apply within a configuration object.

$sel:properties:Configuration', configuration_properties - A set of properties specified within a configuration classification.

configuration_classification :: Lens' Configuration (Maybe Text)

The classification within a configuration.

configuration_configurations :: Lens' Configuration (Maybe [Configuration])

A list of additional configurations to apply within a configuration object.

configuration_properties :: Lens' Configuration (Maybe (HashMap Text Text))

A set of properties specified within a configuration classification.
