AWS::EMR::Cluster MetricDimension
MetricDimension
is a subproperty of the CloudWatchAlarmDefinition
property type. MetricDimension
specifies a CloudWatch dimension, which is specified with a Key
Value
pair. The key is known as a Name
in CloudWatch. 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 automatic scaling rule for EMR to bootstrap when the cluster ID becomes available during cluster creation.
