MetricDimension
A CloudWatch dimension, which is specified using a Key
(known as a
Name
in CloudWatch), Value
pair. By default, Amazon EMR uses
one dimension whose Key
is JobFlowID
and Value
is a
variable representing the cluster ID, which is ${emr.clusterId}
. This enables
the rule to bootstrap when the cluster ID becomes available.
