Overview

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

InstanceTypeConfig is a sub-property of InstanceFleetConfig . InstanceTypeConfig determines the EC2 instances that Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities.

Constructor Details

#initialize(instance_type:, bid_price: nil, bid_price_as_percentage_of_on_demand_price: nil, configurations: nil, custom_ami_id: nil, ebs_configuration: nil, priority: nil, weighted_capacity: nil) ⇒ InstanceTypeConfigProperty

Returns a new instance of InstanceTypeConfigProperty.

Parameters:

  • instance_type (String) —

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

  • bid_price (String, nil) (defaults to: nil) —

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

  • bid_price_as_percentage_of_on_demand_price (Numeric, nil) (defaults to: nil) —

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

  • configurations (AWSCDK::IResolvable, Array<AWSCDK::IResolvable, AWSCDK::EMR::CfnCluster::ConfigurationProperty>, nil) (defaults to: nil) —

    A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.

  • custom_ami_id (String, nil) (defaults to: nil) —

    The custom AMI ID to use for the instance type.

  • ebs_configuration (AWSCDK::IResolvable, AWSCDK::EMR::CfnCluster::EbsConfigurationProperty, nil) (defaults to: nil) —

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

  • priority (Numeric, nil) (defaults to: nil) —

    The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type.

  • weighted_capacity (Numeric, nil) (defaults to: nil) —

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