#target_on_demand_capacity ⇒ Integer
The target capacity of On-Demand units for the instance fleet, which
determines how many On-Demand Instances to provision. When the
instance fleet launches, Amazon EMR tries to provision On-Demand
Instances as specified by InstanceTypeConfig. Each instance
configuration has a specified WeightedCapacity
. When an On-Demand
Instance is provisioned, the WeightedCapacity
units count toward
the target capacity. Amazon EMR provisions instances until the
target capacity is totally fulfilled, even if this results in an
overage. For example, if there are 2 units remaining to fulfill
capacity, and Amazon EMR can only provision an instance with a
WeightedCapacity
of 5 units, the instance is provisioned, and the
target capacity is exceeded by 3 units.
TargetSpotCapacity
. At least one of
TargetSpotCapacity
and TargetOnDemandCapacity
should be greater
than 0. For a master instance fleet, only one of
TargetSpotCapacity
and TargetOnDemandCapacity
can be specified,
and its value must be 1.

#target_spot_capacity ⇒ Integer
The target capacity of Spot units for the instance fleet, which
determines how many Spot Instances to provision. When the instance
fleet launches, Amazon EMR tries to provision Spot Instances as
specified by InstanceTypeConfig. Each instance configuration has a
specified WeightedCapacity
. When a Spot Instance is provisioned,
the WeightedCapacity
units count toward the target capacity.
Amazon EMR provisions instances until the target capacity is totally
fulfilled, even if this results in an overage. For example, if there
are 2 units remaining to fulfill capacity, and Amazon EMR can only
