Method Details

getInstanceTypeConfigs

public final Object getInstanceTypeConfigs()

Description copied from interface: CfnCluster.InstanceFleetConfigProperty

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

Specified by:

getInstanceTypeConfigs in interface CfnCluster.InstanceFleetConfigProperty

getLaunchSpecifications

public final Object getLaunchSpecifications()

Description copied from interface: CfnCluster.InstanceFleetConfigProperty

The launch specification for the instance fleet.

Specified by:

getLaunchSpecifications in interface CfnCluster.InstanceFleetConfigProperty

getName

public final String getName()

Description copied from interface: CfnCluster.InstanceFleetConfigProperty

The friendly name of the instance fleet.

Specified by:

getName in interface CfnCluster.InstanceFleetConfigProperty

getTargetOnDemandCapacity

public final Number getTargetOnDemandCapacity()

Description copied from interface: CfnCluster.InstanceFleetConfigProperty

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.

Specified by:

getTargetOnDemandCapacity in interface CfnCluster.InstanceFleetConfigProperty

getTargetSpotCapacity

public final Number getTargetSpotCapacity()

Description copied from interface: CfnCluster.InstanceFleetConfigProperty

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.
