I have printed out the opts below the Launch slaves(the launch script is stopped at here), is it normal? opts: {'ami': 'ami-4517dc2c', 'ft': 1, 'branch': 'master', 'zone': 'eu-west-1a', 'resume': False, 'ebs_vol_size': 0, 'master_instance_type': '', 'identity_file': 'awskey.pem', 'proxy_port': None, 'instance_type': 'm1.large', 'key_pair': 'awskey', 'swap': 1024, 'slaves': 1, 'download': 'none', 'spot_price': None, 'os': 'amazon64', 'wait': 60} Do you have idea how to fix it? Any helps would be appreciated! Best regards, ./mesos-ec2 -k awskey -i awskey.pem --zone=eu-west-1a launch test01-mesos Setting up security groups... Checking for running cluster...
