Method Details

instanceTypeConfigs

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder instanceTypeConfigs(IResolvable instanceTypeConfigs)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getInstanceTypeConfigs()

Parameters:

instanceTypeConfigs - The instance type configurations that define the Amazon EC2 instances in the instance fleet.

Returns:

this

instanceTypeConfigs

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder instanceTypeConfigs(List<? extends Object> instanceTypeConfigs)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getInstanceTypeConfigs()

Parameters:

instanceTypeConfigs - The instance type configurations that define the Amazon EC2 instances in the instance fleet.

Returns:

this

launchSpecifications

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder launchSpecifications(IResolvable launchSpecifications)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getLaunchSpecifications()

Parameters:

launchSpecifications - The launch specification for the instance fleet.

Returns:

this

launchSpecifications

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder launchSpecifications(CfnCluster.InstanceFleetProvisioningSpecificationsProperty launchSpecifications)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getLaunchSpecifications()

Parameters:

launchSpecifications - The launch specification for the instance fleet.

Returns:

this

name

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder name(String name)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getName()

Parameters:

name - The friendly name of the instance fleet.

Returns:

this

targetOnDemandCapacity

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder targetOnDemandCapacity(Number targetOnDemandCapacity)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getTargetOnDemandCapacity()

Parameters:

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.

Returns:

this

targetSpotCapacity

@Stability(Stable)
public CfnCluster.InstanceFleetConfigProperty.Builder targetSpotCapacity(Number targetSpotCapacity)

Sets the value of CfnCluster.InstanceFleetConfigProperty.getTargetSpotCapacity()

Parameters:

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.

Returns:

this
