Properties
Applies only to Amazon EMR AMI versions 3.x and 2.x. For Amazon EMR releases 4.0 and later, ReleaseLabel
is used. To specify a custom AMI, use CustomAmiID
.
An IAM role for automatic scaling policies. The default role is EMR_AutoScaling_DefaultRole
. The IAM role provides a way for the automatic scaling feature to get the required permissions it needs to launch and terminate Amazon EC2 instances in an instance group.
A list of the bootstrap actions run by the job flow.
Describes the execution status of the job flow.
Describes the Amazon EC2 instances of the job flow.
The IAM role that was specified when the job flow was launched. The Amazon EC2 instances of the job flow assume this role.
The KMS key used for encrypting log files. This attribute is only available with Amazon EMR 5.30.0 and later, excluding 6.0.0.
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
available only in Amazon EMR releases 4.1.0 and later, and is the default for releases of Amazon EMR earlier than 5.1.0.
The IAM role that is assumed by the Amazon EMR service to access Amazon Web Services resources on your behalf.
A list of steps run by the job flow.
A list of strings set by third-party software when the job flow is launched. If you are not using third-party software to manage the job flow, this value is empty.
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 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 principals.
