It is unclear whether the destroy function works because it always gives the same output:

NEXT/ec2 git/CLI
❯ next --key-pair=next_key_1 --identity-file=next_key_1.pem --instance-type=c3.8xlarge destroy jordan_dev

cluster_name : jordan_dev

Are you sure you want to destroy the cluster jordan_dev?
The following instances will be terminated:
Searching for existing cluster jordan_dev...
ALL DATA ON ALL NODES WILL BE LOST!!
Destroy cluster jordan_dev (y/N): y
Terminating master...
Terminating slaves...
