getAutoScalingRole

public final String getAutoScalingRole()

Description copied from interface: CfnClusterProps

An IAM role for automatic scaling policies.

The default role is EMR_AutoScaling_DefaultRole . The IAM role provides permissions that the automatic scaling feature requires to launch and terminate EC2 instances in an instance group.

Specified by:

getAutoScalingRole in interface CfnClusterProps

getAutoTerminationPolicy

public final Object getAutoTerminationPolicy()

Description copied from interface: CfnClusterProps

`AWS::EMR::Cluster.AutoTerminationPolicy`.

Specified by:

getAutoTerminationPolicy in interface CfnClusterProps

getBootstrapActions

public final Object getBootstrapActions()

Description copied from interface: CfnClusterProps

A list of bootstrap actions to run before Hadoop starts on the cluster nodes.

Specified by:

getBootstrapActions in interface CfnClusterProps

getConfigurations

public final Object getConfigurations()

Description copied from interface: CfnClusterProps

Applies only to Amazon EMR releases 4.x and later. The list of Configurations supplied to the EMR cluster.

Specified by:

getConfigurations in interface CfnClusterProps

getCustomAmiId

public final String getCustomAmiId()

Description copied from interface: CfnClusterProps

Available only in Amazon EMR version 5.7.0 and later. The ID of a custom Amazon EBS-backed Linux AMI if the cluster uses a custom AMI.

Specified by:

getCustomAmiId in interface CfnClusterProps

getEbsRootVolumeSize

public final Number getEbsRootVolumeSize()

Description copied from interface: CfnClusterProps

The size, in GiB, of the Amazon EBS root device volume of the Linux AMI that is used for each EC2 instance.

Available in Amazon EMR version 4.x and later.

Specified by:

getEbsRootVolumeSize in interface CfnClusterProps

getKerberosAttributes

public final Object getKerberosAttributes()

Description copied from interface: CfnClusterProps

Attributes for Kerberos configuration when Kerberos authentication is enabled using a security configuration.

For more information see Use Kerberos Authentication in the Amazon EMR Management Guide .

Specified by:

getKerberosAttributes in interface CfnClusterProps

getLogEncryptionKmsKeyId

public final String getLogEncryptionKmsKeyId()

Description copied from interface: CfnClusterProps

The AWS KMS key used for encrypting log files.

This attribute is only available with EMR version 5.30.0 and later, excluding EMR 6.0.0.

Specified by:

getLogEncryptionKmsKeyId in interface CfnClusterProps

getLogUri

public final String getLogUri()

Description copied from interface: CfnClusterProps

The path to the Amazon S3 location where logs for this cluster are stored.

Specified by:

getLogUri in interface CfnClusterProps

getManagedScalingPolicy

public final Object getManagedScalingPolicy()

Description copied from interface: CfnClusterProps

Creates or updates a managed scaling policy for an Amazon EMR cluster.

The managed scaling policy defines the limits for resources, such as EC2 instances that can be added or terminated from a cluster. The policy only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

Specified by:

getManagedScalingPolicy in interface CfnClusterProps

getReleaseLabel

public final String getReleaseLabel()

Description copied from interface: CfnClusterProps

The Amazon EMR release label, which determines the version of open-source application packages installed on the cluster.

Release labels are in the form emr-x.x.x , where x.x.x is an Amazon EMR release version such as emr-5.14.0 . For more information about Amazon EMR release versions and included application versions and features, see . The release label applies only to Amazon EMR releases version 4.0 and later. Earlier versions use AmiVersion .

Specified by:

getReleaseLabel in interface CfnClusterProps

getScaleDownBehavior

public final String getScaleDownBehavior()

Description copied from interface: CfnClusterProps

The way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized.

TERMINATE_AT_INSTANCE_HOUR indicates that Amazon EMR terminates nodes at the instance-hour boundary, regardless of when the request to terminate the instance was submitted. This option is only available with Amazon EMR 5.1.0 and later and is the default for clusters created using that version. TERMINATE_AT_TASK_COMPLETION indicates that Amazon EMR adds nodes to a deny list and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. TERMINATE_AT_TASK_COMPLETION is available only in Amazon EMR version 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

Specified by:

getScaleDownBehavior in interface CfnClusterProps

getSecurityConfiguration

public final String getSecurityConfiguration()

Description copied from interface: CfnClusterProps

The name of the security configuration applied to the cluster.

Specified by:

getSecurityConfiguration in interface CfnClusterProps

getStepConcurrencyLevel

public final Number getStepConcurrencyLevel()

Description copied from interface: CfnClusterProps

Specifies the number of steps that can be executed concurrently.

The default value is 1 . The maximum value is 256 .

Specified by:

getStepConcurrencyLevel in interface CfnClusterProps

getSteps

public final Object getSteps()

Description copied from interface: CfnClusterProps

A list of steps to run.

Specified by:

getSteps in interface CfnClusterProps

getTags

public final List<CfnTag> getTags()

Description copied from interface: CfnClusterProps

A list of tags associated with a cluster.

Specified by:

getTags in interface CfnClusterProps

getVisibleToAllUsers

public final Object getVisibleToAllUsers()

Description copied from interface: CfnClusterProps

Indicates whether the cluster is visible to all IAM users of the AWS account associated with the cluster.

If this value is set to true , all IAM users of that AWS account can view and manage the cluster if they have the proper policy permissions set. If this value is false , only the IAM user that created the cluster can view and manage it. This value can be changed using the SetVisibleToAllUsers action.

When you create clusters directly through the EMR console or API, this value is set to true by default. However, for AWS::EMR::Cluster resources in CloudFormation, the default is false .

Specified by:

getVisibleToAllUsers in interface CfnClusterProps
