pub struct AddJobFlowStepsFluentBuilder { /* private fields */ }Expand description
Fluent builder constructing a request to AddJobFlowSteps.
AddJobFlowSteps adds new steps to a running cluster. A maximum of 256 steps are allowed in each job flow.
If your cluster is long-running (such as a Hive data warehouse) or complex, you may require more than 256 steps to process your data. You can bypass the 256-step limitation in various ways, including using SSH to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop.
A step specifies the location of a JAR file stored either on the master node of the cluster or in Amazon S3. Each step is performed by the main function of the main class of the JAR file. The main class can be specified either in the manifest of the JAR or by using the MainFunction parameter of the step.
Amazon EMR executes each step in the order listed. For a step to be considered complete, the main function must exit with a zero exit code and all Hadoop jobs started while the step was running must have completed and run successfully.
You can only add steps to a cluster that is in one of the following states: STARTING, BOOTSTRAPPING, RUNNING, or WAITING.
The string values passed into HadoopJarStep object cannot exceed a total of 10240 characters.
Implementations§
Source§impl AddJobFlowStepsFluentBuilder
impl AddJobFlowStepsFluentBuilder
Sourcepub fn as_input(&self) -> &AddJobFlowStepsInputBuilder
pub fn as_input(&self) -> &AddJobFlowStepsInputBuilder
Access the AddJobFlowSteps as a reference.
Sourcepub async fn send(
self,
) -> Result<AddJobFlowStepsOutput, SdkError<AddJobFlowStepsError, HttpResponse>>
pub async fn send( self, ) -> Result<AddJobFlowStepsOutput, SdkError<AddJobFlowStepsError, HttpResponse>>
Sends the request and returns the response.
If an error occurs, an SdkError will be returned with additional details that
can be matched against.
By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.
Sourcepub fn customize(
self,
) -> CustomizableOperation<AddJobFlowStepsOutput, AddJobFlowStepsError, Self>
pub fn customize( self, ) -> CustomizableOperation<AddJobFlowStepsOutput, AddJobFlowStepsError, Self>
Consumes this builder, creating a customizable operation that can be modified before being sent.
Sourcepub fn job_flow_id(self, input: impl Into<String>) -> Self
pub fn job_flow_id(self, input: impl Into<String>) -> Self
A string that uniquely identifies the job flow. This identifier is returned by RunJobFlow and can also be obtained from ListClusters.
Sourcepub fn set_job_flow_id(self, input: Option<String>) -> Self
pub fn set_job_flow_id(self, input: Option<String>) -> Self
A string that uniquely identifies the job flow. This identifier is returned by RunJobFlow and can also be obtained from ListClusters.
Sourcepub fn get_job_flow_id(&self) -> &Option<String>
pub fn get_job_flow_id(&self) -> &Option<String>
A string that uniquely identifies the job flow. This identifier is returned by RunJobFlow and can also be obtained from ListClusters.
Sourcepub fn steps(self, input: StepConfig) -> Self
pub fn steps(self, input: StepConfig) -> Self
Appends an item to Steps.
To override the contents of this collection use set_steps.
A list of StepConfig to be executed by the job flow.
Sourcepub fn set_steps(self, input: Option<Vec<StepConfig>>) -> Self
pub fn set_steps(self, input: Option<Vec<StepConfig>>) -> Self
A list of StepConfig to be executed by the job flow.
Sourcepub fn get_steps(&self) -> &Option<Vec<StepConfig>>

A list of StepConfig to be executed by the job flow.
Sourcepub fn execution_role_arn(self, input: impl Into<String>) -> Self
pub fn execution_role_arn(self, input: impl Into<String>) -> Self
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.
Sourcepub fn set_execution_role_arn(self, input: Option<String>) -> Self
pub fn set_execution_role_arn(self, input: Option<String>) -> Self
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.
Sourcepub fn get_execution_role_arn(&self) -> &Option<String>
pub fn get_execution_role_arn(&self) -> &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.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
