Struct aws_sdk_emr::model::HadoopJarStepConfig

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

A job flow 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.

properties: Option<Vec<KeyValue>>

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.

jar: Option<String>

A path to a JAR file run 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.

args: Option<Vec<String>>

A list of command line arguments passed to the JAR file's main function when executed.

Implementations

impl HadoopJarStepConfig

pub fn properties(&self) -> Option<&[KeyValue]>

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.

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

A path to a JAR file run during the step.

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]>

A list of command line arguments passed to the JAR file's main function when executed.
