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.
Example
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

instanceType
Type:
string
An Amazon EC2 instance type, such as m3.xlarge
.
bidPrice?
Type:
string
(optional)
The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType
.
Expressed in USD. If neither BidPrice
nor BidPriceAsPercentageOfOnDemandPrice
is provided, BidPriceAsPercentageOfOnDemandPrice
defaults to 100%.
bidPriceAsPercentageOfOnDemandPrice?
Type:
number
(optional)
The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType
.
Expressed as a number (for example, 20 specifies 20%). If neither BidPrice
nor BidPriceAsPercentageOfOnDemandPrice
is provided, BidPriceAsPercentageOfOnDemandPrice
defaults to 100%.
configurations?
Type:

IResolvable
|
Configuration
[]
(optional)
A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.
customAmiId?
Type:
string
(optional)
The custom AMI ID to use for the instance type.
ebsConfiguration?
Type:
IResolvable
|
Ebs
(optional)
The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType
.
priority?
Type:
number
(optional)
The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type.
Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.
weightedCapacity?
Type:
number
(optional)
The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig
.
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.
