Interface CfnInstanceFleetConfig.IInstanceTypeConfigProperty

InstanceType config is a subproperty of InstanceFleetConfig .

Namespace: Amazon.CDK.AWS.EMR

Assembly: Amazon.CDK.AWS.EMR.dll

Syntax (csharp)

public interface IInstanceTypeConfigProperty

Syntax (vb)

Public Interface IInstanceTypeConfigProperty

Remarks

An instance type configuration specifies each instance type in an instance fleet. The configuration determines the EC2 instances Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Synopsis

Properties

BidPrice	The bid price for each Amazon EC2 Spot Instance type as defined by `InstanceType` .
BidPriceAsPercentageOfOnDemandPrice	The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by `InstanceType` .
Configurations	Amazon EMR releases 4.x or later.
CustomAmiId	The custom AMI ID to use for the instance type.
EbsConfiguration	The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by `InstanceType` .
InstanceType	An Amazon EC2 instance type, such as `m3.xlarge` .
WeightedCapacity	The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in `InstanceFleetConfig` .

Properties

BidPrice

The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType .

virtual string BidPrice { get; }

Property Value

System.String

Remarks

Expressed in USD. If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.

BidPriceAsPercentageOfOnDemandPrice

The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType .

virtual Nullable<double> BidPriceAsPercentageOfOnDemandPrice { get; }

Property Value

System.Nullable<System.Double>

Remarks

Expressed as a number (for example, 20 specifies 20%). If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.

Configurations

Amazon EMR releases 4.x or later.

virtual object Configurations { get; }

Property Value

System.Object

Remarks

An optional configuration specification to be used when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR. A configuration consists of a classification, properties, and optional nested configurations. A classification refers to an application-specific configuration file. Properties are the settings you want to change in that file. For more information, see Configuring Applications .

CustomAmiId

The custom AMI ID to use for the instance type.

virtual string CustomAmiId { get; }

Property Value

System.String

Remarks

EbsConfiguration

The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType .

virtual object EbsConfiguration { get; }

Property Value

System.Object

Remarks

InstanceType

An Amazon EC2 instance type, such as m3.xlarge .

string InstanceType { get; }

Property Value

System.String

Remarks

WeightedCapacity

The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig .

virtual Nullable<double> WeightedCapacity { get; }

Property Value

System.Nullable<System.Double>

Remarks

This value is 1 for a master instance fleet, and must be 1 or greater for core and task instance fleets. Defaults to 1 if not specified.
