the class EmrPricingHelper method updateEmrClusterDefinitionWithBestPrice.

/**
 * Finds the best price for each master and core instances based on the subnets and master and core instance search parameters given in the definition.
 * <p/>
 * The results of the findings are used to update the given definition.
 * <p/>
 * If the instance's instanceSpotPrice is set, the instance definition will keep that value. If the instance's instanceMaxSearchPrice is set, the best price
 * will be found. If the found price is spot, the instanceSpotPrice will be set to the value of instanceMaxSearchPrice. If the found price is on-demand, the
 * instanceSpotPrice will be removed. The definition's subnetId will be set to the particular subnet which the best price is found. The value will always be
 * replaced by a single subnet ID.
 * <p/>
 * The definition's instanceMaxSearchPrice and instanceOnDemandThreshold will be removed by this operation.
