Struct aws_sdk_emr::types::HadoopStepConfig

#[non_exhaustive]
pub struct HadoopStepConfig { /* private fields */ }

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.

Implementations

impl HadoopStepConfig

pub fn jar(&self) -> Option<&str>

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

pub fn properties(&self) -> Option<&HashMap<String, String>>

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.

pub fn main_class(&self) -> Option<&str>

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.

pub fn args(&self) -> Option<&[String]>

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

impl HadoopStepConfig

pub fn builder() -> HadoopStepConfigBuilder

Creates a new builder-style object to manufacture HadoopStepConfig.

Trait Implementations

impl Clone for HadoopStepConfig

fn clone(&self) -> HadoopStepConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HadoopStepConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<HadoopStepConfig> for HadoopStepConfig

fn eq(&self, other: &HadoopStepConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
