Ec2InstanceAttributes class

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

Properties

additionalMasterSecurityGroups → List<String>?
A list of additional Amazon EC2 security group IDs for the master node.
final
additionalSlaveSecurityGroups → List<String>?
A list of additional Amazon EC2 security group IDs for the core and task nodes.
final
ec2AvailabilityZone → String?
The Availability Zone in which the cluster will run.
final
ec2KeyName → String?
The name of the Amazon EC2 key pair to use when connecting with SSH into the master node as a user named "hadoop".
final
ec2SubnetId → String?
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.
final
emrManagedMasterSecurityGroup → String?
The identifier of the Amazon EC2 security group for the master node.
final
emrManagedSlaveSecurityGroup → String?
The identifier of the Amazon EC2 security group for the core and task nodes.
final
hashCode → int
The hash code for this object.
no setterinherited
iamInstanceProfile → String?
The IAM role that was specified when the cluster was launched. The EC2 instances of the cluster assume this role.
final
requestedEc2AvailabilityZones → List<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.
final
requestedEc2SubnetIds → List<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.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
serviceAccessSecurityGroup → String?
The identifier of the Amazon EC2 security group for the Amazon EMR service to access clusters in VPC private subnets.
final

Methods
