    Parameters:
    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.
  - withProperties
```
public HadoopStepConfig withProperties(Map<String,String> 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.
    Returns a reference to this object so that method calls can be chained together.
    
    Parameters:
    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.
    
    Returns:
    A reference to this updated object so that method calls can be chained together.
