NAME

Paws::EMR::JobFlowInstancesConfig

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::JobFlowInstancesConfig object:

  $service_obj->Method(Att1 => { AdditionalMasterSecurityGroups => $value, ..., TerminationProtected => $value  });

Results returned from an API call

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

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

DESCRIPTION

A description of the Amazon EC2 instance on which the cluster (job flow) runs. A valid JobFlowInstancesConfig must contain either InstanceGroups or InstanceFleets, which is the recommended configuration. They cannot be used together. You may also have MasterInstanceType, SlaveInstanceType, and InstanceCount (all three must be present), but we don't recommend this configuration.

ATTRIBUTES

AdditionalMasterSecurityGroups => ArrayRef[Str|Undef]

  A list of additional Amazon EC2 security group IDs for the master node.

AdditionalSlaveSecurityGroups => ArrayRef[Str|Undef]

  A list of additional Amazon EC2 security group IDs for the slave nodes.

Ec2KeyName => Str

  The name of the EC2 key pair that can be used to ssh to the master node
as the user called "hadoop."

Ec2SubnetId => Str

  Applies to clusters that use the uniform instance group configuration.
To launch the cluster in Amazon Virtual Private Cloud (Amazon VPC), set
this parameter to the identifier of the Amazon VPC subnet where you
want the cluster to launch. If you do not specify this value, the
cluster launches in the normal Amazon Web Services cloud, outside of an
Amazon VPC, if the account launching the cluster supports EC2 Classic
networks in the region where the cluster launches.

Amazon VPC currently does not support cluster compute quadruple extra large (cc1.4xlarge) instances. Thus you cannot specify the cc1.4xlarge instance type for clusters launched in an Amazon VPC.

Ec2SubnetIds => ArrayRef[Str|Undef]

  Applies to clusters that use the instance fleet configuration. When
multiple EC2 subnet IDs are specified, Amazon EMR evaluates them and
launches instances in the optimal subnet.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

EmrManagedMasterSecurityGroup => Str

  The identifier of the Amazon EC2 security group for the master node.

EmrManagedSlaveSecurityGroup => Str

  The identifier of the Amazon EC2 security group for the slave nodes.

HadoopVersion => Str

  The Hadoop version for the cluster. Valid inputs are "0.18"
(deprecated), "0.20" (deprecated), "0.20.205" (deprecated), "1.0.3",
"2.2.0", or "2.4.0". If you do not set this value, the default of 0.18
is used, unless the AmiVersion parameter is set in the RunJobFlow call,
in which case the default version of Hadoop for that AMI version is
used.

InstanceCount => Int

  The number of EC2 instances in the cluster.

InstanceFleets => ArrayRef[Paws::EMR::InstanceFleetConfig]

  The instance fleet configuration is available only in Amazon EMR
versions 4.8.0 and later, excluding 5.0.x versions.

Describes the EC2 instances and instance configurations for clusters that use the instance fleet configuration.

InstanceGroups => ArrayRef[Paws::EMR::InstanceGroupConfig]

  Configuration for the instance groups in a cluster.

KeepJobFlowAliveWhenNoSteps => Bool

  Specifies whether the cluster should remain available after completing
all steps.

MasterInstanceType => Str

  The EC2 instance type of the master node.

Placement => Paws::EMR::PlacementType

  The Availability Zone in which the cluster runs.

ServiceAccessSecurityGroup => Str

  The identifier of the Amazon EC2 security group for the Amazon EMR
service to access clusters in VPC private subnets.

SlaveInstanceType => Str

  The EC2 instance type of the slave nodes.

TerminationProtected => Bool

  Specifies whether to lock the cluster to prevent the Amazon EC2
instances from being terminated by API call, user intervention, or in
the event of a job-flow error.
