Struct aws_sdk_emr::types::StepConfig

#[non_exhaustive]
pub struct StepConfig {
    pub name: Option<String>,

    pub hadoop_jar_step: Option<HadoopJarStepConfig>,
}

Specification for a cluster (job flow) step.

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.

name: Option<String>

The name of the step.

action_on_failure: Option<ActionOnFailure>

The action to take when the step fails. Use one of the following values:

• TERMINATE_CLUSTER - Shuts down the cluster.

• CANCEL_AND_WAIT - Cancels any pending steps and returns the cluster to the WAITING state.

• CONTINUE - Continues to the next step in the queue.

• TERMINATE_JOB_FLOW - Shuts down the cluster. TERMINATE_JOB_FLOW is provided for backward compatibility. We recommend using TERMINATE_CLUSTER instead.

If a cluster's StepConcurrencyLevel is greater than 1, do not use AddJobFlowSteps to submit a step with this parameter set to CANCEL_AND_WAIT or TERMINATE_CLUSTER. The step is not submitted and the action fails with a message that the ActionOnFailure setting is not valid.

If you change a cluster's StepConcurrencyLevel to be greater than 1 while a step is running, the ActionOnFailure parameter may not behave as you expect. In this case, for a step that fails with this parameter set to CANCEL_AND_WAIT, pending steps and the running step are not canceled; for a step that fails with this parameter set to TERMINATE_CLUSTER, the cluster does not terminate.

hadoop_jar_step: Option<HadoopJarStepConfig>

The JAR file used for the step.

Implementations

impl StepConfig

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

The name of the step.

pub fn action_on_failure(&self) -> Option<&ActionOnFailure>

The action to take when the step fails. Use one of the following values:

• TERMINATE_CLUSTER - Shuts down the cluster.

• CANCEL_AND_WAIT - Cancels any pending steps and returns the cluster to the WAITING state.

• CONTINUE - Continues to the next step in the queue.

• TERMINATE_JOB_FLOW - Shuts down the cluster. TERMINATE_JOB_FLOW is provided for backward compatibility. We recommend using TERMINATE_CLUSTER instead.

If a cluster's StepConcurrencyLevel is greater than 1, do not use AddJobFlowSteps to submit a step with this parameter set to CANCEL_AND_WAIT or TERMINATE_CLUSTER. The step is not submitted and the action fails with a message that the ActionOnFailure setting is not valid.

If you change a cluster's StepConcurrencyLevel to be greater than 1 while a step is running, the ActionOnFailure parameter may not behave as you expect. In this case, for a step that fails with this parameter set to CANCEL_AND_WAIT, pending steps and the running step are not canceled; for a step that fails with this parameter set to TERMINATE_CLUSTER, the cluster does not terminate.

pub fn hadoop_jar_step(&self) -> Option<&HadoopJarStepConfig>

The JAR file used for the step.

impl StepConfig

pub fn builder() -> StepConfigBuilder

Creates a new builder-style object to manufacture StepConfig.

Trait Implementations

impl Clone for StepConfig

fn clone(&self) -> StepConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StepConfig

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

Formats the value using the given formatter.

impl PartialEq for StepConfig

fn eq(&self, other: &StepConfig) -> 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.
