Struct aws_sdk_emr::types::Step

#[non_exhaustive]
pub struct Step {
    pub id: Option<String>,
    pub name: Option<String>,
    pub config: Option<HadoopStepConfig>,
    pub action_on_failure: Option<ActionOnFailure>,
    pub status: Option<StepStatus>,
    pub execution_role_arn: Option<String>,
}

This represents a step in a cluster.

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.

id: Option<String>

The identifier of the cluster step.

name: Option<String>

The name of the cluster step.

config: Option<HadoopStepConfig>

The Hadoop job configuration of the cluster step.

action_on_failure: Option<ActionOnFailure>

The action to take when the cluster step fails. Possible values are TERMINATE_CLUSTER, CANCEL_AND_WAIT, and CONTINUE. 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.

status: Option<StepStatus>

The current execution status details of the cluster step.

execution_role_arn: Option<String>

The Amazon Resource Name (ARN) of the runtime role for a step on the cluster. The runtime role can be a cross-account IAM role. The runtime role ARN is a combination of account ID, role name, and role type using the following format: arn:partition:service:region:account:resource.

For example, arn:aws:IAM::1234567890:role/ReadOnly is a correctly formatted runtime role ARN.

Implementations

impl Step

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

The identifier of the cluster step.

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

The name of the cluster step.

pub fn config(&self) -> Option<&HadoopStepConfig>

The Hadoop job configuration of the cluster step.

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

The action to take when the cluster step fails. Possible values are TERMINATE_CLUSTER, CANCEL_AND_WAIT, and CONTINUE. 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.

pub fn status(&self) -> Option<&StepStatus>

impl Step

pub fn builder() -> StepBuilder

Creates a new builder-style object to manufacture Step.

Trait Implementations

impl Clone for Step

fn clone(&self) -> Step

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Step

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

Formats the value using the given formatter.

impl PartialEq for Step

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