data InstanceGroup Source #

This entity represents an instance group, which is a group of instances that have common purpose. For example, CORE instance group is used for HDFS.

See: newInstanceGroup smart constructor.

Constructors

InstanceGroup'

Fields

status :: Maybe InstanceGroupStatus
The current status of the instance group.
lastSuccessfullyAppliedConfigurationsVersion :: Maybe Integer
The version number of a configuration specification that was successfully applied for an instance group last time.
bidPrice :: Maybe Text
If specified, indicates that the instance group uses Spot Instances. This is the maximum price you are willing to pay for Spot Instances. Specify OnDemandPrice to set the amount equal to the On-Demand price, or specify an amount in USD.
requestedInstanceCount :: Maybe Int
The target number of instances for the instance group.
runningInstanceCount :: Maybe Int
The number of instances currently running in this instance group.
lastSuccessfullyAppliedConfigurations :: Maybe [Configuration]
A list of configurations that were successfully applied for an instance group last time.
configurations :: Maybe [Configuration]
Amazon EMR releases 4.x or later.
The list of configurations supplied for an Amazon EMR cluster instance group. You can specify a separate configuration for each instance group (master, core, and task).
customAmiId :: Maybe Text
The custom AMI ID to use for the provisioned instance group.
instanceGroupType :: Maybe InstanceGroupType
The type of the instance group. Valid values are MASTER, CORE or TASK.
ebsBlockDevices :: Maybe [EbsBlockDevice]
The EBS block devices that are mapped to this instance group.
instanceType :: Maybe Text
The EC2 instance type for all instances in the instance group.
configurationsVersion :: Maybe Integer
The version number of the requested configuration specification for this instance group.
ebsOptimized :: Maybe Bool
If the instance group is EBS-optimized. An Amazon EBS-optimized instance uses an optimized configuration stack and provides additional, dedicated capacity for Amazon EBS I/O.
market :: Maybe MarketType
The marketplace to provision instances for this group. Valid values are ON_DEMAND or SPOT.
name :: Maybe Text
The name of the instance group.
autoScalingPolicy :: Maybe AutoScalingPolicyDescription
An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.
shrinkPolicy :: Maybe ShrinkPolicy
Policy for customizing shrink operations.
id :: Maybe Text
The identifier of the instance group.
