Documentation

data HadoopStepConfig Source #

A cluster 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: newHadoopStepConfig smart constructor.

Constructors

HadoopStepConfig'

Fields

args :: Maybe [Text]
The list of command line arguments to pass to the JAR file's main function for execution.
jar :: Maybe Text
The path to the JAR file that runs during the step.
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 (HashMap Text Text)
The 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.

newHadoopStepConfig :: HadoopStepConfig Source #

Create a value of HadoopStepConfig 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:HadoopStepConfig', hadoopStepConfig_args - The list of command line arguments to pass to the JAR file's main function for execution.

$sel:jar:HadoopStepConfig', hadoopStepConfig_jar - The path to the JAR file that runs during the step.

$sel:mainClass:HadoopStepConfig', hadoopStepConfig_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:HadoopStepConfig', hadoopStepConfig_properties - The 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.

hadoopStepConfig_args :: Lens' HadoopStepConfig (Maybe [Text]) Source #

The list of command line arguments to pass to the JAR file's main function for execution.

hadoopStepConfig_jar :: Lens' HadoopStepConfig (Maybe Text) Source #

The path to the JAR file that runs during the step.

hadoopStepConfig_mainClass :: Lens' HadoopStepConfig (Maybe Text) Source #

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.

hadoopStepConfig_properties :: Lens' HadoopStepConfig (Maybe (HashMap Text Text)) Source #

The 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.
