How can I set root device EBS volume of EMR cluster using Cloud Formation Script

Question

I want to launch an AWS EMR cluster using AWS Cloud Formation Script. I am not able to set Root device EBS volume size. By default it creates a volume of size 10 GB. I want my cluster should have 50 GB Root Device EBS volume.
