=head1 NAME

Paws::EMR::Ec2InstanceAttributes

=head1 USAGE

This class represents one of two things:

=head3 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::Ec2InstanceAttributes object:

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

=head3 Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::Ec2InstanceAttributes object:

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

=head1 DESCRIPTION

Provides information about the EC2 instances in a cluster grouped by
category. For example, key name, subnet ID, IAM instance profile, and
so on.

=head1 ATTRIBUTES


=head2 AdditionalMasterSecurityGroups => ArrayRef[Str|Undef]

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


=head2 AdditionalSlaveSecurityGroups => ArrayRef[Str|Undef]

A list of additional Amazon EC2 security group IDs for the core and
task nodes.


=head2 Ec2AvailabilityZone => Str

The Availability Zone in which the cluster will run.


=head2 Ec2KeyName => Str

The name of the Amazon EC2 key pair to use when connecting with SSH
into the master node as a user named "hadoop".


=head2 Ec2SubnetId => Str

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, and your
account supports EC2-Classic, the cluster launches in EC2-Classic.


=head2 EmrManagedMasterSecurityGroup => Str

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


=head2 EmrManagedSlaveSecurityGroup => Str

The identifier of the Amazon EC2 security group for the core and task
nodes.


=head2 IamInstanceProfile => Str

The IAM role that was specified when the cluster was launched. The EC2
instances of the cluster assume this role.


=head2 RequestedEc2AvailabilityZones => ArrayRef[Str|Undef]

Applies to clusters configured with the instance fleets option.
Specifies one or more Availability Zones in which to launch EC2 cluster
instances when the EC2-Classic network configuration is supported.
Amazon EMR chooses the Availability Zone with the best fit from among
the list of C<RequestedEc2AvailabilityZones>, and then launches all
cluster instances within that Availability Zone. If you do not specify
this value, Amazon EMR chooses the Availability Zone for you.
C<RequestedEc2SubnetIDs> and C<RequestedEc2AvailabilityZones> cannot be
specified together.


=head2 RequestedEc2SubnetIds => ArrayRef[Str|Undef]

Applies to clusters configured with the instance fleets option.
Specifies the unique identifier of one or more Amazon EC2 subnets in
which to launch EC2 cluster instances. Subnets must exist within the
same VPC. Amazon EMR chooses the EC2 subnet with the best fit from
among the list of C<RequestedEc2SubnetIds>, and then launches all
cluster instances within that Subnet. If this value is not specified,
and the account and Region support EC2-Classic networks, the cluster
launches instances in the EC2-Classic network and uses
C<RequestedEc2AvailabilityZones> instead of this setting. If
EC2-Classic is not supported, and no Subnet is specified, Amazon EMR
chooses the subnet for you. C<RequestedEc2SubnetIDs> and
C<RequestedEc2AvailabilityZones> cannot be specified together.


=head2 ServiceAccessSecurityGroup => Str

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