Paws::EMR::InstanceGroup(3) User Contributed Perl Documentation Paws::EMR::InstanceGroup(3)

Paws::EMR::InstanceGroup

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::EMR::InstanceGroup object:

  $service_obj->Method(Att1 => { AutoScalingPolicy => $value, ..., Status => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::InstanceGroup object:

  $result = $service_obj->Method(...);
  $result->Att1->AutoScalingPolicy

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.

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.

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.

Amazon EMR releases 4.x or later.

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).

The version number of the requested configuration specification for this instance group.

The EBS block devices that are mapped to this instance group.

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.

The identifier of the instance group.

The type of the instance group. Valid values are MASTER, CORE or TASK.

The EC2 instance type for all instances in the instance group.

A list of configurations that were successfully applied for an instance group last time.

The version number of a configuration specification that was successfully applied for an instance group last time.

The marketplace to provision instances for this group. Valid values are ON_DEMAND or SPOT.

The name of the instance group.

The target number of instances for the instance group.

The number of instances currently running in this instance group.

Policy for customizing shrink operations.

The current status of the instance group.

This class forms part of Paws, describing an object used in Paws::EMR
