Method Detail

getAdditionalMasterSecurityGroups

@Stability(value=Experimental)
 @Nullable
default List<String> getAdditionalMasterSecurityGroups()

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

Default: - None

getAdditionalSlaveSecurityGroups

@Stability(value=Experimental)
 @Nullable
default List<String> getAdditionalSlaveSecurityGroups()

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

Default: - None

getEc2KeyName

@Stability(value=Experimental)
 @Nullable
default String getEc2KeyName()

(experimental) The name of the EC2 key pair that can be used to ssh to the master node as the user called "hadoop.".

Default: - None

getEc2SubnetId

@Stability(value=Experimental)
 @Nullable
default String getEc2SubnetId()

(experimental) Applies to clusters that use the uniform instance group configuration.

To launch the cluster in Amazon Virtual Private Cloud (Amazon VPC), set this parameter to the identifier of the Amazon VPC subnet where you want the cluster to launch.

Default: EMR selected default

getEc2SubnetIds

@Stability(value=Experimental)
 @Nullable
default List<String> getEc2SubnetIds()

(experimental) Applies to clusters that use the instance fleet configuration.

When multiple EC2 subnet IDs are specified, Amazon EMR evaluates them and launches instances in the optimal subnet.

Default: EMR selected default

getEmrManagedMasterSecurityGroup

@Stability(value=Experimental)
 @Nullable
default String getEmrManagedMasterSecurityGroup()

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

Default: - None

getEmrManagedSlaveSecurityGroup

@Stability(value=Experimental)
 @Nullable
default String getEmrManagedSlaveSecurityGroup()

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

Default: - None

getHadoopVersion

@Stability(value=Experimental)
 @Nullable
default String getHadoopVersion()

(experimental) Applies only to Amazon EMR release versions earlier than 4.0. The Hadoop version for the cluster.

Default: - 0.18 if the AmiVersion parameter is not set. If AmiVersion is set, the version of Hadoop for that AMI version is used.

getInstanceCount

@Stability(value=Experimental)
 @Nullable
default Number getInstanceCount()

(experimental) The number of EC2 instances in the cluster.

Default: 0

getInstanceFleets

@Stability(value=Experimental)
 @Nullable
default List<EmrCreateCluster.InstanceFleetConfigProperty> getInstanceFleets()

(experimental) Describes the EC2 instances and instance configurations for clusters that use the instance fleet configuration.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Default: - None

getInstanceGroups

@Stability(value=Experimental)
 @Nullable
default List<EmrCreateCluster.InstanceGroupConfigProperty> getInstanceGroups()

(experimental) Configuration for the instance groups in a cluster.

Default: - None

getMasterInstanceType

@Stability(value=Experimental)
 @Nullable
default String getMasterInstanceType()

(experimental) The EC2 instance type of the master node.

Default: - None

getPlacement

@Stability(value=Experimental)
 @Nullable
default EmrCreateCluster.PlacementTypeProperty getPlacement()

(experimental) The Availability Zone in which the cluster runs.

Default: - EMR selected default

getServiceAccessSecurityGroup

@Stability(value=Experimental)
 @Nullable
default String getServiceAccessSecurityGroup()

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

Default: - None

getSlaveInstanceType

@Stability(value=Experimental)
 @Nullable
default String getSlaveInstanceType()

(experimental) The EC2 instance type of the core and task nodes.

Default: - None

getTerminationProtected

@Stability(value=Experimental)
 @Nullable
default Boolean getTerminationProtected()

(experimental) Specifies whether to lock the cluster to prevent the Amazon EC2 instances from being terminated by API call, user intervention, or in the event of a job-flow error.

Default: false
