Specify the type of Amazon EC2 instances that the cluster (job flow) runs on.

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.

master_instance_type: Option<String>

The Amazon EC2 master node instance type.

master_public_dns_name: Option<String>

The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.

master_instance_id: Option<String>

The Amazon EC2 instance identifier of the master node.

slave_instance_type: Option<String>

The Amazon EC2 core and task node instance type.

instance_count: Option<i32>

The number of Amazon EC2 instances in the cluster. If the value is 1, the same instance serves as both the master and core and task node. If the value is greater than 1, one instance is the master node and all others are core and task nodes.

instance_groups: Option<Vec<InstanceGroupDetail>>

Details about the instance groups in a cluster.

normalized_instance_hours: Option<i32>

An approximation of the cost of the cluster, represented in m1.small/hours. This value is increased one time for every hour that an m1.small instance runs. Larger instances are weighted more heavily, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being increased incrementally four times. This result is only an approximation and does not reflect the actual billing rate.

ec2_key_name: Option<String>

The name of an Amazon EC2 key pair that can be used to connect to the master node using SSH.

ec2_subnet_id: Option<String>

For clusters launched within Amazon Virtual Private Cloud, this is the identifier of the subnet where the cluster was launched.

placement: Option<PlacementType>

The Amazon EC2 Availability Zone for the cluster.

keep_job_flow_alive_when_no_steps: Option<bool>

Specifies whether the cluster should remain available after completing all steps.

termination_protected: Option<bool>

Specifies whether the Amazon EC2 instances in the cluster are protected from termination by API calls, user intervention, or in the event of a job-flow error.

hadoop_version: Option<String>

The Hadoop version for the cluster.

Implementations

impl JobFlowInstancesDetail

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

The Amazon EC2 master node instance type.

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

The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.

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

The Amazon EC2 instance identifier of the master node.

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

The Amazon EC2 core and task node instance type.

pub fn instance_count(&self) -> Option<i32>

The number of Amazon EC2 instances in the cluster. If the value is 1, the same instance serves as both the master and core and task node. If the value is greater than 1, one instance is the master node and all others are core and task nodes.

pub fn instance_groups(&self) -> &[InstanceGroupDetail]

Details about the instance groups in a cluster.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .instance_groups.is_none().

pub fn normalized_instance_hours(&self) -> Option<i32>

An approximation of the cost of the cluster, represented in m1.small/hours. This value is increased one time for every hour that an m1.small instance runs. Larger instances are weighted more heavily, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being increased incrementally four times. This result is only an approximation and does not reflect the actual billing rate.

pub fn ec2_key_name(&self) -> Option<&str>

The name of an Amazon EC2 key pair that can be used to connect to the master node using SSH.

pub fn ec2_subnet_id(&self) -> Option<&str>

For clusters launched within Amazon Virtual Private Cloud, this is the identifier of the subnet where the cluster was launched.

pub fn placement(&self) -> Option<&PlacementType>

The Amazon EC2 Availability Zone for the cluster.

pub fn keep_job_flow_alive_when_no_steps(&self) -> Option<bool>

Specifies whether the cluster should remain available after completing all steps.

pub fn termination_protected(&self) -> Option<bool>

Specifies whether the Amazon EC2 instances in the cluster are protected from termination by API calls, user intervention, or in the event of a job-flow error.

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

The Hadoop version for the cluster.

impl JobFlowInstancesDetail

pub fn builder() -> JobFlowInstancesDetailBuilder

Creates a new builder-style object to manufacture JobFlowInstancesDetail.

Trait Implementations

impl Clone for JobFlowInstancesDetail

fn clone(&self) -> JobFlowInstancesDetail

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JobFlowInstancesDetail

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

Formats the value using the given formatter.

impl PartialEq for JobFlowInstancesDetail

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