Method Detail

name

public String name()

The friendly name of the instance fleet.

Returns:

The friendly name of the instance fleet.

instanceFleetType

public InstanceFleetType instanceFleetType()

The node type that the instance fleet hosts. Valid values are MASTER,CORE,and TASK.

If the service returns an enum value that is not available in the current SDK version, instanceFleetType will return InstanceFleetType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceFleetTypeAsString().

Returns:

The node type that the instance fleet hosts. Valid values are MASTER,CORE,and TASK.

instanceFleetTypeAsString

public String instanceFleetTypeAsString()

The node type that the instance fleet hosts. Valid values are MASTER,CORE,and TASK.

If the service returns an enum value that is not available in the current SDK version, instanceFleetType will return InstanceFleetType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceFleetTypeAsString().

Returns:

The node type that the instance fleet hosts. Valid values are MASTER,CORE,and TASK.

targetOnDemandCapacity

public Integer 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:

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.

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.

targetSpotCapacity

public Integer 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.
