Synopsis

Properties

InstanceFleetType

The node type that the instance fleet hosts.
InstanceTypeConfigs

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

The launch specification for the instance fleet.
Name

The friendly name of the instance fleet.
TargetOnDemandCapacity

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

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

Properties

InstanceFleetType

The node type that the instance fleet hosts.

EmrCreateCluster.InstanceRoleType InstanceFleetType { get; }
Property Value

EmrCreateCluster.InstanceRoleType

Remarks

Valid values are MASTER,CORE,and TASK.

InstanceTypeConfigs

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

virtual EmrCreateCluster.IInstanceTypeConfigProperty[] InstanceTypeConfigs { get; }
Property Value

EmrCreateCluster.IInstanceTypeConfigProperty[]

Remarks

Default: No instanceTpeConfigs

LaunchSpecifications

The launch specification for the instance fleet.

virtual EmrCreateCluster.IInstanceFleetProvisioningSpecificationsProperty LaunchSpecifications { get; }
Property Value

EmrCreateCluster.IInstanceFleetProvisioningSpecificationsProperty

Remarks

Default: No launchSpecifications

Name

The friendly name of the instance fleet.

virtual string Name { get; }
Property Value

System.String

Remarks

Default: No name

TargetOnDemandCapacity

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

virtual Nullable<double> TargetOnDemandCapacity { get; }
Property Value

System.Nullable<System.Double>

Remarks

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.

Default: No targetOnDemandCapacity

TargetSpotCapacity

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

virtual Nullable<double> TargetSpotCapacity { get; }
Property Value

System.Nullable<System.Double>

Remarks

If not specified or set to 0, only On-Demand Instances are provisioned for the instance fleet using targetOnDemandCapacity.

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.

Default: No targetSpotCapacity
