Defined in:: emr/cfn_cluster.rb

Overview

Use InstanceGroupConfig to define instance groups for an EMR cluster.

A cluster can not use both instance groups and instance fleets. For more information, see Create a Cluster with Instance Fleets or Uniform Instance Groups in the Amazon EMR Management Guide .

Constructor Details

#initialize(instance_count:, instance_type:, auto_scaling_policy: nil, bid_price: nil, configurations: nil, custom_ami_id: nil, ebs_configuration: nil, market: nil, name: nil) ⇒ `InstanceGroupConfigProperty`

Returns a new instance of InstanceGroupConfigProperty.

Parameters:

instance_count (Numeric) —
Target number of instances for the instance group.
instance_type (String) —
The Amazon EC2 instance type for all instances in the instance group.
auto_scaling_policy (AWSCDK::IResolvable, AWSCDK::EMR::CfnCluster::AutoScalingPolicyProperty, nil) (defaults to: nil) —
AutoScalingPolicy is a subproperty of the InstanceGroupConfig property type that specifies the constraints and rules of an automatic scaling policy in Amazon EMR . The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. Only core and task instance groups can use automatic scaling policies. For more information, see Using Automatic Scaling in Amazon EMR .
bid_price (String, nil) (defaults to: nil) —
If specified, indicates that the instance group uses Spot Instances.
configurations (AWSCDK::IResolvable, Array<AWSCDK::IResolvable, AWSCDK::EMR::CfnCluster::ConfigurationProperty>, nil) (defaults to: nil) —

Amazon EMR releases 4.x or later.
custom_ami_id (String, nil) (defaults to: nil) —
The custom AMI ID to use for the provisioned instance group.
ebs_configuration (AWSCDK::IResolvable, AWSCDK::EMR::CfnCluster::EbsConfigurationProperty, nil) (defaults to: nil) —
EBS configurations that will be attached to each Amazon EC2 instance in the instance group.
market (String, nil) (defaults to: nil) —
Market type of the Amazon EC2 instances used to create a cluster node.
name (String, nil) (defaults to: nil) —
Friendly name given to the instance group.
