When passing HadoopJarStepConfig as input to an Aws::Client method, you can use a vanilla Hash:

{
  properties: [
    {
      key: "XmlString",
      value: "XmlString",
    },
  ],
  jar: "XmlString",   main_class: "XmlString",
  args: ["XmlString"],
}

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.

Returned by:

• #args ⇒ Array<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.

• #main_class ⇒ String

  The name of the main class in the specified Java file.

• #properties ⇒ Array<Types::KeyValue>

  A list of Java properties that are set when the step runs.

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

A path to a JAR file run during the step.

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.
