We are excited to announce our new API Documentation.
The detailed description of the cluster.
The applications installed on this cluster.
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 Amazon EC2 instances in an instance group.
Specifies whether the cluster should terminate after completing all steps.
The Amazon Resource Name of the cluster.
Applies only to Amazon EMR releases 4.x and later. The list of configurations that are supplied to the Amazon EMR cluster.
Available only in Amazon EMR releases 5.7.0 and later. The ID of a custom Amazon EBS-backed Linux AMI if the cluster uses a custom AMI.
The size, in GiB, of the Amazon EBS root device volume of the Linux AMI that is used for each Amazon EC2 instance. Available in Amazon EMR releases 4.x and later.
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.
The unique identifier for the cluster.
The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.
The instance group configuration of the cluster. A value of
indicates a uniform instance group configuration. A value of
indicates an instance fleets configuration.
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.
The 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.
The path to the Amazon S3 location where logs for this cluster are stored.
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.
The name of the cluster.
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.
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.
The Amazon Resource Name (ARN) of the Outpost where the cluster is launched.
Placement group configured for an Amazon EMR cluster.
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
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
The AMI version requested for this cluster.
The AMI version running on this cluster.
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
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.
The name of the security configuration applied to the cluster.
The IAM role that Amazon EMR assumes in order to access Amazon Web Services resources on your behalf.
The current status details about the cluster.
Specifies the number of steps that can be executed concurrently.
A list of tags associated with a cluster.
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.
Indicates whether the cluster is visible to IAM principals in the Amazon Web Services account associated with the cluster. When
true, IAM principals in the Amazon Web Services 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 Amazon Web Services account root user can perform Amazon EMR actions, regardless
of IAM permissions policies attached to other IAM
The default value is
true if a value is not provided when creating a
cluster using the Amazon EMR API RunJobFlow command, the CLI
create-cluster command, or the Amazon Web Services Management Console.
