There are two billing methods available for E-MapReduce: Pay-As-You-Go and Subscription. We recommend that you use Pay-As-You-Go, as it is more cost-effective. If you are sure that you want to use E-MapReduce for a longer period of time, you can change to the Subscription method.
Convert Pay-As-You-Go to Subscription
You can select the Pay-As-You-Go method at the beginning during your E-MapReduce trial and at any time after that. In the Cluster Overview panel, click the Switch to Subscription button to switch your payment method from Pay-As-You-Go to Subscription. The payment method for the entire cluster will be converted.
Convert Subscription to Pay-As-You-Go
You cannot currently convert from Subscription to Pay-As-You-Go.
