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.

Method Detail

classification

public final String classification()

The classification within a configuration.

Returns:

The classification within a configuration.

hasConfigurations

public final boolean hasConfigurations()

For responses, this returns true if the service returned a value for the Configurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

configurations

public final List<Configuration> configurations()

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

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasConfigurations() method.

Returns:

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

hasProperties

public final boolean hasProperties()

For responses, this returns true if the service returned a value for the Properties property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

properties

public final Map<String,String> properties()

A set of properties specified within a configuration classification.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasProperties() method.

Returns:

A set of properties specified within a configuration classification.

toBuilder

public Configuration.Builder toBuilder()

Specified by:

toBuilder in interface ToCopyableBuilder<Configuration.Builder,Configuration>

builder

public static Configuration.Builder builder()

serializableBuilderClass

public static Class<? extends Configuration.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

hashCode in class Object

equals

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Specified by:

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public final <T> Optional<T> getValueForField(String fieldName,
                                              Class<T> clazz)

sdkFields
