Documentation

data HadoopJarStepConfig

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.

See: newHadoopJarStepConfig smart constructor.

Constructors

HadoopJarStepConfig'

Fields

• args :: Maybe [Text]

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

• mainClass :: Maybe Text

  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.

• properties :: Maybe [KeyValue]

  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.

• jar :: Text

  A path to a JAR file run during the step.

-> HadoopJarStepConfig

Create a value of HadoopJarStepConfig with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:args:HadoopJarStepConfig', hadoopJarStepConfig_args - A list of command line arguments passed to the JAR file's main function when executed.

$sel:mainClass:HadoopJarStepConfig', hadoopJarStepConfig_mainClass - 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.

$sel:properties:HadoopJarStepConfig', hadoopJarStepConfig_properties - 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.

$sel:jar:HadoopJarStepConfig', hadoopJarStepConfig_jar - A path to a JAR file run during the step.

hadoopJarStepConfig_args :: Lens' HadoopJarStepConfig (Maybe [Text])

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

hadoopJarStepConfig_mainClass :: Lens' HadoopJarStepConfig (Maybe Text)

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.

hadoopJarStepConfig_properties :: Lens' HadoopJarStepConfig (Maybe [KeyValue])
