Properties

ec2KeyName → String?

The name of an Amazon EC2 key pair that can be used to connect to the master node using SSH.

final

ec2SubnetId → String?

For clusters launched within Amazon Virtual Private Cloud, this is the identifier of the subnet where the cluster was launched.

final

hadoopVersion → String?

The Hadoop version for the cluster.

final

hashCode → int

The hash code for this object.

no setter, inherited

instanceCount → int

The number of Amazon EC2 instances in the cluster. If the value is 1, the same instance serves as both the master and core and task node. If the value is greater than 1, one instance is the master node and all others are core and task nodes.

final

instanceGroups → List<InstanceGroupDetail>?

Details about the instance groups in a cluster.

final

keepJobFlowAliveWhenNoSteps → bool?

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

final

masterInstanceId → String?

The Amazon EC2 instance identifier of the master node.

final

masterInstanceType → String

The Amazon EC2 master node instance type.

final

masterPublicDnsName → String?

The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.

final

normalizedInstanceHours → int?

An approximation of the cost of the cluster, represented in m1.small/hours. This value is increased one time for every hour that an m1.small instance runs. Larger instances are weighted more heavily, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being increased incrementally four times. This result is only an approximation and does not reflect the actual billing rate.

final

placement → PlacementType?

The Amazon EC2 Availability Zone for the cluster.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

slaveInstanceType → String

The Amazon EC2 core and task node instance type.

final

terminationProtected → bool?

Specifies whether the Amazon EC2 instances in the cluster are protected from termination by API calls, user intervention, or in the event of a job-flow error.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
