Constructor Detail

HadoopJarStepConfig

public HadoopJarStepConfig()

Default constructor for a new HadoopJarStepConfig object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.

HadoopJarStepConfig

public HadoopJarStepConfig(String jar)

Constructs a new HadoopJarStepConfig object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

jar - A path to a JAR file run during the step.

Method Detail

getProperties

public List<KeyValue> getProperties()

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.

Returns:

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.

setProperties

public void setProperties(Collection<KeyValue> 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.

Parameters:

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.

withProperties

public HadoopJarStepConfig withProperties(KeyValue... 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.

Returns a reference to this object so that method calls can be chained together.

Parameters:

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.

withProperties

public HadoopJarStepConfig withProperties(Collection<KeyValue> 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.
