Interface EmrCreateCluster.ISimpleScalingPolicyConfigurationProperty
An automatic scaling configuration, which describes how the policy adds or removes instances, the cooldown period, and the number of EC2 instances that will be added each time the CloudWatch metric alarm condition is satisfied.

Synopsis
Properties
AdjustmentType | The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. |
CoolDown | The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. |
ScalingAdjustment | The amount by which to scale in or scale out, based on the specified AdjustmentType. |
Properties
AdjustmentType
The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered.
virtual Nullable<EmrCreateCluster.ScalingAdjustmentType> AdjustmentType { get; }
Property Value
System.Nullable<EmrCreateCluster.ScalingAdjustmentType>
Remarks
Default: - None
CoolDown
The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start.
virtual Nullable<double> CoolDown { get; }
Property Value
System.Nullable<System.Double>
Remarks
Default: 0
ScalingAdjustment
The amount by which to scale in or scale out, based on the specified AdjustmentType.
double ScalingAdjustment { get; }
Property Value
System.Double
Remarks
A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer.
