Interface CfnCluster.HadoopJarStepConfigProperty

All Superinterfaces:

software.amazon.jsii.JsiiSerializable

All Known Implementing Classes:

CfnCluster.HadoopJarStepConfigProperty.Jsii$Proxy

Enclosing class:

CfnCluster

@Stability(Stable)
public static interface CfnCluster.HadoopJarStepConfigProperty
extends software.amazon.jsii.JsiiSerializable

The HadoopJarStepConfig property type specifies a job flow step consisting of a JAR file whose main function will be executed.

The main function submits a job for the cluster to execute as a step on the master node, and then waits for the job to finish or fail before executing subsequent steps.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 HadoopJarStepConfigProperty hadoopJarStepConfigProperty = HadoopJarStepConfigProperty.builder()
         .jar("jar")
         // the properties below are optional
         .args(List.of("args"))
         .mainClass("mainClass")
         .stepProperties(List.of(KeyValueProperty.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();

getJar

@Stability(Stable)
@NotNull
String getJar()

A path to a JAR file run during the step.

getArgs

@Stability(Stable)
@Nullable
default List<String> getArgs()

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

getMainClass

@Stability(Stable)
@Nullable
default String getMainClass()

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.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-emr-cluster-hadoopjarstepconfig.html#cfn-emr-cluster-hadoopjarstepconfig-mainclass

getStepProperties

@Stability(Stable)
@Nullable
default Object getStepProperties()

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.

Returns union: either IResolvable or Listinvalid input: '<'either IResolvable or CfnCluster.KeyValueProperty>

builder

@Stability(Stable)
static CfnCluster.HadoopJarStepConfigProperty.Builder builder()

Returns:

a CfnCluster.HadoopJarStepConfigProperty.Builder of CfnCluster.HadoopJarStepConfigProperty
