@Generated(value="software.amazon.awssdk:codegen")
public final class HadoopJarStepConfig
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<HadoopJarStepConfig.Builder,HadoopJarStepConfig>

A job flow step consisting of a JAR file whose main function will be executed. The main function submits a job for Hadoop to execute and waits for the job to finish or fail.

Method Detail

hasProperties

public final boolean hasProperties()

Returns true if the Properties property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

properties

public final List<KeyValue> properties()

A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.

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

You can use hasProperties() to see if a value was sent in this field.

Returns:

A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.

jar

public final String jar()

A path to a JAR file run during the step.

Returns:

A path to a JAR file run during the step.

mainClass

public final String mainClass()

The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.

Returns:

The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.

hasArgs

public final boolean hasArgs()

Returns true if the Args property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

args

public final List<String> args()

A list of command line arguments passed to the JAR file's main function when executed.

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

You can use hasArgs() to see if a value was sent in this field.

Returns:

A list of command line arguments passed to the JAR file's main function when executed.

toBuilder

public HadoopJarStepConfig.Builder toBuilder()

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<HadoopJarStepConfig.Builder,HadoopJarStepConfig>

Returns:

a builder for type T

builder

public static HadoopJarStepConfig.Builder builder()

serializableBuilderClass

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

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

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

public final List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
