TargetSpotCapacity - The target capacity of Spot units for the instance fleet, which determines how many Spot Instances to provision.The WeightedCapacity specified for an instance type within InstanceTypeConfigs counts toward this total when an instance type with the On-Demand purchasing option launches. TargetOnDemandCapacity - The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand Instances to provision.InstanceFleetType - MASTER, CORE, or TASK.- An optional friendly name for the instance fleet.
The following arguments can be specified for each instance fleet. You can specify arguments individually using multiple InstanceFleetType argument blocks, one for the MASTER instance fleet, one for a CORE instance fleet, and an optional TASK instance fleet.
For more information and examples, see the following topic in the Amazon EMR Management Guide: You can specify either -instance-fleets or -instance-groups but not both. Specifies the number and type of Amazon EC2 instances to create for each node type in a cluster, using instance fleets. "AdjustmentType": "CHANGE_IN_CAPACITY"|"PERCENT_CHANGE_IN_CAPACITY"|"EXACT_CAPACITY",Īpplies only to Amazon EMR release version 5.0 and later. "InstanceGroupType": "MASTER"|"CORE"|"TASK",
- Specifies an automatic scaling policy for the instance group using an inline JSON structure. - Specifies additional Amazon EBS storage volumes attached to EC2 instances using an inline JSON structure. Specify OnDemandPrice to set the amount equal to the On-Demand price, or specify an amount in USD. This is the maximum price you are willing to pay for Spot Instances. - If specified, indicates that the instance group uses Spot Instances. InstanceCount - The number of EC2 instances to provision in the instance group. InstanceType - The type of EC2 instance, for example m4.large, to use for all nodes in the instance group. 
InstanceGroupType - MASTER, CORE, or TASK. - An optional friendly name for the instance group. If you specify inline JSON structures, enclose the entire InstanceGroupType argument block in single quotation marks.Įach InstanceGroupType block takes the following inline arguments. You can specify arguments individually using multiple InstanceGroupType argument blocks, one for the MASTER instance group, one for a CORE instance group, and optional, multiple TASK instance groups. For more information, see the following topic in the EMR Management Guide: You can specify either -instance-groups or -instance-fleets but not both. Specifies the number and type of Amazon EC2 instances to create for each node type in a cluster, using uniform instance groups. instance-fleets | -instance-groups | -instance-type -instance-count
