Zeppelin install step failing

[stvoutsin]

Tried a deploy and I'm getting this error:

  TASK [Download and install Zeppelin] *******************************************
  fatal: [zeppelin]: FAILED! => {"changed": false, "msg": "Failure downloading https://object.arcus.openstack.hpc.cam.ac.uk/swift/v1/...../archive/zeppelin-0.10.1-gaia-dmp-0.1.tar.gz, Request failed: <urlopen error [Errno 113] No route to host>"}

Presumably the doanload is happening on the zeppelin node itself ?
In which case, can you login to that node and see if you can do the download manually ?
Which will tell us if it is a permanent failure or an intermittent one.
