sytemd-hostnamed service is failing in coreos-1520.6.0

[je...@srcclr.com]

I was trying set the hostname using hostnamectl but it threw following error.

"ip-10-1-1-154 jeeva # hostnamectl set-hostname k8s-worker-1507708889.ops1.srcclr.com

Could not set property: Failed to activate service 'org.freedesktop.hostname1': timed out"

systemd-hostname.service also failed.

logs --

"ct 13 04:24:14 ip-10-1-1-154.us-west-2.compute.internal systemd[1]: systemd-hostnamed.service: Main process exited, code=exited, status=226/NAMESPACE

Oct 13 04:24:14 ip-10-1-1-154.us-west-2.compute.internal systemd[1]: Failed to start Hostname Service.

Oct 13 04:24:14 ip-10-1-1-154.us-west-2.compute.internal systemd[1]: systemd-hostnamed.service: Unit entered failed state."

All the systemd files are updated on Oct12th.  Our application depends on the hostname and at the moment I could revert the AWS issued hostname with ours

OS - coreos-1520.6.0

systemd - 234
