      Sets the value of CfnInstanceFleetConfigProps.getClusterId()
      Parameters:
      clusterId - The unique identifier of the EMR cluster. This parameter is required.
      Returns:
      this

    • instanceFleetType

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder instanceFleetType(String instanceFleetType)
      Sets the value of CfnInstanceFleetConfigProps.getInstanceFleetType()
      Parameters:
      instanceFleetType - The node type that the instance fleet hosts. This parameter is required. Allowed Values : TASK
      Returns:
      this

    • instanceTypeConfigs

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder instanceTypeConfigs(IResolvable instanceTypeConfigs)
      Sets the value of CfnInstanceFleetConfigProps.getInstanceTypeConfigs()
      Parameters:
      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.

      Returns:
      this

    • instanceTypeConfigs

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder instanceTypeConfigs(List<? extends Object> instanceTypeConfigs)
      Sets the value of CfnInstanceFleetConfigProps.getInstanceTypeConfigs()
      Parameters:
      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.

      Returns:
      this

    • launchSpecifications

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder launchSpecifications(IResolvable launchSpecifications)
      Sets the value of CfnInstanceFleetConfigProps.getLaunchSpecifications()
      Parameters:
      launchSpecifications - The launch specification for the instance fleet.
      Returns:
      this

    • launchSpecifications

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder launchSpecifications(CfnInstanceFleetConfig.InstanceFleetProvisioningSpecificationsProperty launchSpecifications)
      Sets the value of CfnInstanceFleetConfigProps.getLaunchSpecifications()
      Parameters:
      launchSpecifications - The launch specification for the instance fleet.
      Returns:
      this

    • name

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder name(String name)
      Sets the value of CfnInstanceFleetConfigProps.getName()
      Parameters:
      name - The friendly name of the instance fleet.
      Returns:
      this

    • targetOnDemandCapacity

      @Stability(Stable) public CfnInstanceFleetConfigProps.Builder targetOnDemandCapacity(Number targetOnDemandCapacity)
      Sets the value of CfnInstanceFleetConfigProps.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 CfnInstanceFleetConfigProps.Builder targetSpotCapacity(Number targetSpotCapacity)
      Sets the value of CfnInstanceFleetConfigProps.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
