Method Detail

ec2KeyName

public String ec2KeyName()

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

Returns:

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

ec2SubnetId

public String ec2SubnetId()

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:

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.

requestedEc2SubnetIds

public List<String> requestedEc2SubnetIds()

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. Amazon EMR chooses the EC2 subnet with the best performance and cost characteristics from among the list of RequestedEc2SubnetIds and launches all cluster instances within that subnet. If this value is not specified, and the account supports EC2-Classic networks, the cluster launches instances in the EC2-Classic network and uses Requested

Returns:

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. Amazon EMR chooses the EC2 subnet with the best performance and cost characteristics from among the list of RequestedEc2SubnetIds and launches all cluster instances within that subnet. If this value is not specified, and the account supports EC2-Classic networks, the cluster launches instances in the EC2-Classic network and uses Requested

ec2AvailabilityZone

public String ec2AvailabilityZone()

The Availability Zone in which the cluster will run.

Returns:

The Availability Zone in which the cluster will run.

requestedEc2AvailabilityZones

public List<String> requestedEc2AvailabilityZones()

Applies to clusters configured with the The list of availability zones to choose from. The service will choose the availability zone with the best mix of available capacity and lowest cost to launch the cluster. If you do not specify this value, the cluster is launched in any availability zone that the customer account has access to.

Returns:

Applies to clusters configured with the The list of availability zones to choose from. The service will choose the availability zone with the best mix of available capacity and lowest cost to launch the cluster. If you do not specify this value, the cluster is launched in any availability zone that the customer account has access to.

iamInstanceProfile

public String iamInstanceProfile()

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

Returns:

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

emrManagedMasterSecurityGroup

public String emrManagedMasterSecurityGroup()

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

Returns:

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

emrManagedSlaveSecurityGroup

public String emrManagedSlaveSecurityGroup()

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

Returns:

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

serviceAccessSecurityGroup

public String serviceAccessSecurityGroup()

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

Returns:

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

additionalMasterSecurityGroups

public List<String> additionalMasterSecurityGroups()

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

Returns:

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

additionalSlaveSecurityGroups

public List<String> additionalSlaveSecurityGroups()

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

Returns:

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