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.

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 releases 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

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 .

Returns union: either Boolean or IResolvable
