Type: Integer

Required: No

The throughput, in MiB/s, of the Amazon EBS root device volume of the Linux AMI that is used for each Amazon EC2 instance. Available in Amazon EMR releases 6.15.0 and later.

Type: Integer

Required: No

Provides information about the Amazon EC2 instances in a cluster grouped by category. For example, key name, subnet ID, IAM instance profile, and so on.

Type: Ec2InstanceAttributes object

Required: No

The unique identifier for the cluster.

Type: String

Required: No

The instance group configuration of the cluster. A value of INSTANCE_GROUP indicates a uniform instance group configuration. A value of INSTANCE_FLEET indicates an instance fleets configuration.

Type: String

Valid Values: INSTANCE_FLEET | INSTANCE_GROUP

Required: No

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.

Type: KerberosAttributes object

Required: No

The AWS KMS key used for encrypting log files. This attribute is only available with Amazon EMR 5.30.0 and later, excluding Amazon EMR 6.0.0.

Type: String

Required: No

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

Type: String

Required: No

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.

Type: String

Required: No

The name of the cluster. This parameter can't contain the characters <, >, $, |, or ` (backtick).

Type: String

Required: No

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

Type: Integer

Required: No

The Amazon Linux release specified in a cluster launch RunJobFlow request. If no Amazon Linux release was specified, the default Amazon Linux release is shown in the response.

Type: String

Required: No

The Amazon Resource Name (ARN) of the Outpost where the cluster is launched.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 2048.

Required: No

Placement group configured for an Amazon EMR cluster.

Type: Array of PlacementGroupConfig objects

Required: No

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 https://docs.aws.amazon.com/emr/latest/ReleaseGuide/. The release label applies only to Amazon EMR releases version 4.0 and later. Earlier versions use AmiVersion.

Type: String

Required: No

Applies only when CustomAmiID is used. Specifies the type of updates that the Amazon Linux AMI package repositories apply when an instance boots using the AMI.

Type: String

Valid Values: SECURITY | NONE

Required: No

The AMI version requested for this cluster.

Type: String

Required: No

The AMI version running on this cluster.

Type: String

Required: No

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

Type: String

Valid Values: TERMINATE_AT_INSTANCE_HOUR | TERMINATE_AT_TASK_COMPLETION

Required: No

The name of the security configuration applied to the cluster.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 10280.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\r\n\t]*

Required: No

The IAM role that Amazon EMR assumes in order to access AWS resources on your behalf.

Type: String

Required: No

The current status details about the cluster.

Type: ClusterStatus object

Required: No

Specifies the number of steps that can be executed concurrently.

Type: Integer

Required: No

A list of tags associated with a cluster.

Type: Array of Tag objects

Required: No

Indicates whether Amazon EMR will lock the cluster to prevent the Amazon EC2 instances from being terminated by an API call or user intervention, or in the event of a cluster error.

Type: Boolean

Required: No

Indicates whether Amazon EMR should gracefully replace Amazon EC2 core instances that have degraded within the cluster.

Type: Boolean

Required: No

Indicates whether the cluster is visible to IAM principals in the AWS account associated with the cluster. When true, IAM principals in the AWS account can perform Amazon EMR cluster actions on the cluster that their IAM policies allow. When false, only the IAM principal that created the cluster and the AWS account root user can perform Amazon EMR actions, regardless of IAM permissions policies attached to other IAM principals.

The default value is true if a value is not provided when creating a cluster using the Amazon EMR API RunJobFlow command, the AWS CLI create-cluster command, or the AWS Management Console.

Type: Boolean

Required: No
