Ansible installer failed to install with setting containerized=false

Issue

• When I ran ansible to install openshift master native-ha, I got following errors:

TASK: [etcd | Enable etcd] ****************************************************
failed: [xxxx.example.com] => {"failed": true}
msg: Error when trying to enable etcd_container: rc=1 Failed to execute operation: Access denied

or

TASK: [openshift_master_ca | Create the master certificates if they do not already exist] ***
failed: [master.example.com] => {"cmd": "/usr/local/bin/oadm create-master-certs --hostnames=kubernetes.default,10.67.112.120,kubernetes.default.svc.cluster.local,kubernetes,openshift.default....}
msg: [Errno 2] No such file or directory

• I set containerized=false in my /etc/ansible/hosts so it should install them as RPM.
