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

#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.
