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 { aws_emr as emr } from '@aws-cdk/cfn-property-mixins';
const hadoopJarStepConfigProperty: emr.CfnClusterPropsMixin.HadoopJarStepConfigProperty = {
  args: ['args'],
  jar: 'jar',
  mainClass: 'mainClass',
  stepProperties: [{
    key: 'key',
    value: 'value',
  }],
};

Properties

Name	Type	Description
args?	`string[]`	A list of command line arguments passed to the JAR file's main function when executed.
jar?	`string`	A path to a JAR file run during the step.
mainClass?	`string`	The name of the main class in the specified Java file.
stepProperties?	`IResolvable` `\| (IResolvable` `\|` `KeyValueProperty)[]`	A list of Java properties that are set when the step runs.

args?

Type: string[] (optional)

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

jar?

Type: string (optional)

A path to a JAR file run during the step.

mainClass?

Type: string (optional)

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.

stepProperties?

Type: IResolvable | (IResolvable | KeyValueProperty)[] (optional)

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.
