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.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { mixins as emr_mixins } from '@aws-cdk/mixins-preview/aws-emr';
const hadoopJarStepConfigProperty: emr_mixins.CfnStepPropsMixin.HadoopJarStepConfigProperty = {
  args: ['args'],
  jar: 'jar',
  mainClass: 'mainClass',
  stepProperties: [{
    key: 'key',
    value: 'value',
  }],
};

Properties

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.
