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