Looks like a connectivity issue. Your hosts file is being found now,
but it seems there's some problem connecting to the hostnames listed
therein. Please ensure you are able to manually ssh to those hosts
from francium. If successful manual ssh requires a different hostname
(e.g. if "ssh host1.cluster.lab" works but "ssh host1" doesn't), you
may want to update your hosts file to reflect that.
