#normalized_instance_hours ⇒ Integer

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 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.

Returns:

Release labels are in the form ‘emr-x.x.x`, where x.x.x is an Amazon EMR release version, for example, `emr-5.14.0`. For more information about Amazon EMR release versions and included application versions and features, see [docs.aws.amazon.com/emr/latest/ReleaseGuide/][1]. The release label applies only to Amazon EMR releases versions 4.x and later. Earlier versions use `AmiVersion`.

end

#scale_down_behavior ⇒ String

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 blacklists 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.

Returns:

  • (String)
