Steve Loughran commented on HADOOP-11390:
-----------------------------------------
I think if it is just unresolved hostname, I'd rather something explicit in the
code that check for it; this should also let us upgrade it to an
UnknownHostException.
{code}
if (addr.isUnresolved()) {
throw new UnknownHostException("Unresolved host: " + addr);
}
{code}
Now, how can test this?
