Struct HadoopStepConfig

#[non_exhaustive]
pub struct HadoopStepConfig {
    pub jar: Option<String>,
    pub properties: Option<HashMap<String, String>>,
    pub main_class: Option<String>,
    pub args: Option<Vec<String>>,
}

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.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

jar: Option<String>

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

properties: 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.

main_class: Option<String>

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.

args: Option<Vec<String>>

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

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) -> &[String]

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

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .args.is_none().

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 for HadoopStepConfig

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

Tests for self and other values to be equal, and is used by ==.

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

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