NAME

Paws::EMR::InstanceGroup

USAGE

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

DESCRIPTION

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.

ATTRIBUTES

AutoScalingPolicy => Paws::EMR::AutoScalingPolicyDescription

  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.

BidPrice => Str

  The bid price for each EC2 instance in the instance group when
launching nodes as Spot Instances, expressed in USD.

Configurations => ArrayRef[Paws::EMR::Configuration]

  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).

EbsBlockDevices => ArrayRef[Paws::EMR::EbsBlockDevice]

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

EbsOptimized => Bool

  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.

Id => Str

  The identifier of the instance group.

InstanceGroupType => Str

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

InstanceType => Str

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

Market => Str

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

Name => Str

  The name of the instance group.

RequestedInstanceCount => Int

  The target number of instances for the instance group.

RunningInstanceCount => Int

  The number of instances currently running in this instance group.

ShrinkPolicy => Paws::EMR::ShrinkPolicy

  Policy for customizing shrink operations.

Status => Paws::EMR::InstanceGroupStatus

  The current status of the instance group.
