#ec2_subnet_idString

To launch the cluster in 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 is launched in the normal AWS cloud, outside of a VPC.

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

Returns:

  • (String)

#requested_ec2_availability_zonesArray<String>

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 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. RequestedEc2SubnetIDs and RequestedEc2AvailabilityZones cannot be specified together.

Returns:

  • (Array<String>)

  include Aws::Structure
end

#requested_ec2_subnet_idsArray<String>

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 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 RequestedEc2AvailabilityZones instead of this setting. If EC2-Classic is not supported, and no Subnet is specified, Amazon EMR chooses the subnet for you. RequestedEc2SubnetIDs and RequestedEc2AvailabilityZones cannot be specified together.

Returns:

  • (Array<String>)
