Todd Lipcon commented on HDFS-2859:
-----------------------------------
bq. A general question I have is whether it is ok for certain name node hosts
to be unresolved during startup. I guess it might be ok because some machines
might legitimately be out of service and disconnected from the network.
I don't think it's OK -- though a loud warning might be enough. Even if the
host is down/disconnected, we'd expect the domain name to be around.
The patch here looks good, though. +1
