Description

Synopsis

Documentation

data PlacementType Source #

The Amazon EC2 Availability Zone configuration of the cluster (job flow).

See: newPlacementType smart constructor.

Constructors

PlacementType'

Fields

availabilityZones :: Maybe [Text]
When multiple Availability Zones are specified, Amazon EMR evaluates them and launches instances in the optimal Availability Zone. AvailabilityZones is used for instance fleets, while AvailabilityZone (singular) is used for uniform instance groups.
The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.
availabilityZone :: Maybe Text
The Amazon EC2 Availability Zone for the cluster. AvailabilityZone is used for uniform instance groups, while AvailabilityZones (plural) is used for instance fleets.
