Struct HadoopStepConfig

pub struct HadoopStepConfig {
    pub args: Option<Vec<String>>,
    pub jar: Option<String>,
    pub main_class: Option<String>,
    pub properties: Option<HashMap<String, 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

args: Option<Vec<String>>

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

jar: Option<String>

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

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.

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.

Trait Implementations

impl Clone for HadoopStepConfig

fn clone(&self) -> HadoopStepConfig

Returns a duplicate 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 Default for HadoopStepConfig

fn default() -> HadoopStepConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HadoopStepConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.
