    #   An approximation of the cost of the cluster, represented in

    #   `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

    #   if it could lead to HDFS corruption. `TERMINATE_AT_TASK_COMPLETION`
