AutoScalingPolicy
AutoScalingPolicy is a subproperty of InstanceGroupConfig .
public object AutoScalingPolicy { get; set; }Property Value
System.Object
Remarks
AutoScalingPolicy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. For more information, see Using Automatic Scaling in Amazon EMR in the Amazon EMR Management Guide .
BidPrice
If specified, indicates that the instance group uses Spot Instances.
public string BidPrice { get; set; }Property Value
System.String
Remarks
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.
Configurations
Amazon EMR releases 4.x or later.
public object Configurations { get; set; }Property Value
System.Object
Remarks
The list of configurations supplied for an EMR cluster instance group. You can specify a separate configuration for each instance group (master, core, and task).
CustomAmiId
The custom AMI ID to use for the provisioned instance group.
public string CustomAmiId { get; set; }Property Value
System.String
Remarks
EbsConfiguration
EbsConfiguration determines the EBS volumes to attach to EMR cluster instances.
public object EbsConfiguration { get; set; }Property Value
System.Object
Remarks
InstanceCount
Target number of instances for the instance group.
public double InstanceCount { get; set; }Property Value
System.Double
Remarks
InstanceRole
The role of the instance group in the cluster.
public string InstanceRole { get; set; }Property Value
System.String
Remarks
InstanceType
The EC2 instance type for all instances in the instance group.
public string InstanceType { get; set; }Property Value
System.String
Remarks
JobFlowId
The ID of an Amazon EMR cluster that you want to associate this instance group with.
public string JobFlowId { get; set; }Property Value
System.String
Remarks
Market
Market type of the EC2 instances used to create a cluster node.
public string Market { get; set; }Property Value
System.String
Remarks
Name
Friendly name given to the instance group.
public string Name { get; set; }Property Value
System.String
