notes
If not specified or set to 0, only Spot Instances are provisioned for the instance fleet using 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.
