Interface CfnCluster.HadoopJarStepConfigProperty

All Known Implementing Classes:

CfnCluster.HadoopJarStepConfigProperty.Jsii$Proxy

Enclosing class:

CfnCluster

public static interface CfnCluster.HadoopJarStepConfigProperty

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();

Method Detail

getJar

java.lang.String getJar()

A path to a JAR file run during the step.

getArgs

default java.util.List<java.lang.String> getArgs()

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

getMainClass

default java.lang.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.

getStepProperties

default java.lang.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.

builder

static CfnCluster.HadoopJarStepConfigProperty.Builder builder()

Returns:

a CfnCluster.HadoopJarStepConfigProperty.Builder of CfnCluster.HadoopJarStepConfigProperty
