Amazonka.EMR.Types.Configuration

Description

Synopsis

Documentation

data Configuration Source #

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

Configuration'
Fields configurations :: Maybe [Configuration] A list of additional configurations to apply within a configuration object. classification :: Maybe Text The classification within a configuration. properties :: Maybe (HashMap Text Text) A set of properties specified within a configuration classification.

newConfiguration :: Configuration Source #

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

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

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

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

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

configuration_classification :: Lens' Configuration (Maybe Text) Source #

The classification within a configuration.

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

A set of properties specified within a configuration classification.
