Instance Attribute Details

#auto_scaling_policy ⇒ Types::AutoScalingPolicy

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 Amazon EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

Returns:

• (Types::AutoScalingPolicy)

  :auto_scaling_policy,
  :custom_ami_id)
  SENSITIVE = []
  include Aws::Structure
end

#bid_price ⇒ String

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.

Returns:

• (String)
