Properties
Name | Type | Description |
---|---|---|
cluster | string | The unique identifier of the EMR cluster. |
instance | string | The node type that the instance fleet hosts. |
instance | IResolvable | IResolvable | Instance [] | InstanceTypeConfigs determine the EC2 instances that Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. |
launch | IResolvable | Instance | The launch specification for the instance fleet. |
name? | string | The friendly name of the instance fleet. |
resize | IResolvable | Instance | The resize specification for the instance fleet. |
target | number | The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision. |

clusterId
Type:
string
The unique identifier of the EMR cluster.
instanceFleetType
Type:
string
The node type that the instance fleet hosts.
Allowed Values : TASK
instanceTypeConfigs?
Type:
IResolvable
|
IResolvable
|
Instance
[]
(optional)
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.
launchSpecifications?
Type:
IResolvable
|
Instance
(optional)
The launch specification for the instance fleet.
name?
Type:
string
(optional)
The friendly name of the instance fleet.
resizeSpecifications?
Type:
IResolvable
|
Instance
(optional)
The resize specification for the instance fleet.
targetOnDemandCapacity?
Type:
number
(optional)
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 ofTargetSpotCapacity
andTargetOnDemandCapacity
should be greater than 0. For a master instance fleet, only one ofTargetSpotCapacity
andTargetOnDemandCapacity
can be specified, and its value must be 1.
targetSpotCapacity?
Type:
number
(optional)
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
andTargetOnDemandCapacity
should be greater than 0. For a master instance fleet, only one ofTargetSpotCapacity
andTargetOnDemandCapacity
can be specified, and its value must be 1.
