Method Detail

create

public static CfnInstanceFleetConfig.Builder create(Construct scope,
                                                    java.lang.String id)

Parameters:

scope - - scope in which this resource is defined. This parameter is required.

id - - scoped id of the resource. This parameter is required.

Returns:

a new instance of CfnInstanceFleetConfig.ConfigurationProperty.Builder.

clusterId

public CfnInstanceFleetConfig.Builder clusterId(java.lang.String clusterId)

The unique identifier of the EMR cluster.

Parameters:

clusterId - The unique identifier of the EMR cluster. This parameter is required.

Returns:

this

instanceFleetType

public CfnInstanceFleetConfig.Builder instanceFleetType(java.lang.String instanceFleetType)

The node type that the instance fleet hosts.

Allowed Values : TASK

Parameters:

instanceFleetType - The node type that the instance fleet hosts. This parameter is required.

Returns:

this

instanceTypeConfigs

public CfnInstanceFleetConfig.Builder instanceTypeConfigs(IResolvable instanceTypeConfigs)

`InstanceTypeConfigs` determine the EC2 instances that 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.

Parameters:

instanceTypeConfigs - `InstanceTypeConfigs` determine the EC2 instances that Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. This parameter is required.

Returns:

this

instanceTypeConfigs

public CfnInstanceFleetConfig.Builder instanceTypeConfigs(java.util.List<? extends java.lang.Object> instanceTypeConfigs)

`InstanceTypeConfigs` determine the EC2 instances that 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.

Parameters:

instanceTypeConfigs - `InstanceTypeConfigs` determine the EC2 instances that Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. This parameter is required.

Returns:

this

launchSpecifications

public CfnInstanceFleetConfig.Builder launchSpecifications(IResolvable launchSpecifications)

The launch specification for the instance fleet.

Parameters:

launchSpecifications - The launch specification for the instance fleet. This parameter is required.

Returns:

this

launchSpecifications

public CfnInstanceFleetConfig.Builder launchSpecifications(CfnInstanceFleetConfig.InstanceFleetProvisioningSpecificationsProperty launchSpecifications)

The launch specification for the instance fleet.

Parameters:

launchSpecifications - The launch specification for the instance fleet. This parameter is required.

Returns:

this

name

public CfnInstanceFleetConfig.Builder name(java.lang.String name)

The friendly name of the instance fleet.

Parameters:

name - The friendly name of the instance fleet. This parameter is required.

Returns:

this

targetOnDemandCapacity

public CfnInstanceFleetConfig.Builder targetOnDemandCapacity(java.lang.Number targetOnDemandCapacity)

The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision.

When the instance fleet launches, Amazon EMR tries to provision On-Demand instances as specified by InstanceTypeConfig . Each instance configuration has a specified WeightedCapacity . When an On-Demand instance is provisioned, the WeightedCapacity units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units.

If not specified or set to 0, only Spot instances are provisioned for the instance fleet using TargetSpotCapacity . At least one of TargetSpotCapacity and TargetOnDemandCapacity should be greater than 0. For a master instance fleet, only one of TargetSpotCapacity and TargetOnDemandCapacity can be specified, and its value must be 1.

Parameters:

targetOnDemandCapacity - The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision. This parameter is required.

Returns:

this

targetSpotCapacity

public CfnInstanceFleetConfig.Builder targetSpotCapacity(java.lang.Number targetSpotCapacity)

The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision.

When the instance fleet launches, Amazon EMR tries to provision Spot instances as specified by InstanceTypeConfig . Each instance configuration has a specified WeightedCapacity . When a Spot instance is provisioned, the WeightedCapacity units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units.

If not specified or set to 0, only On-Demand instances are provisioned for the instance fleet. At least one of TargetSpotCapacity and TargetOnDemandCapacity should be greater than 0. For a master instance fleet, only one of TargetSpotCapacity and TargetOnDemandCapacity can be specified, and its value must be 1.

Parameters:

targetSpotCapacity - The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision. This parameter is required.

Returns:

this
