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

A builder for StepConfig

Implementations

impl Builder

pub fn name(self, input: impl Into<String>) -> Self

The name of the step.

pub fn set_name(self, input: Option<String>) -> Self

The name of the step.

pub fn action_on_failure(self, input: ActionOnFailure) -> Self

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 set_action_on_failure(self, input: Option<ActionOnFailure>) -> Self

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.

pub fn hadoop_jar_step(self, input: HadoopJarStepConfig) -> Self

The JAR file used for the step.

pub fn set_hadoop_jar_step(self, input: Option<HadoopJarStepConfig>) -> Self

The JAR file used for the step.

pub fn build(self) -> StepConfig

Consumes the builder and constructs a StepConfig

Trait Implementations

impl Clone for Builder

fn clone(&self) -> Builder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.

impl PartialEq<Builder> for Builder

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