I've seen bonded implementations too, but because I have non-bonded
hosts on the LAN, I don't think I can do that without investing in new
network hardware.

I've never seen anyone do this before, so I can't say. But as long as
the hostname resolves to an appropriate IP it should work. Keep in
mind, that things register in ZK by IP address so you're not really
going to see that much impact in that regard. Furthermore, the
majority of the network use is going to be HDFS, and I really don't
have the knowledge to make a call on how that will behave, but my
hopes aren't high that this sort of optimization will help either.
Traditionally in these setups, I've seen the two NICs bonded. Let the
lower OS levels handle the traffic management IMO.

I currently have eight worker machines are on two Gbit LANs. Right
now, they are configured:
10.10.0.0/24 <http://10.10.0.0/24> with cloud1=10.10.0.11 ...
cloud8=10.10.0.18 ... plus a small number of other machines
10.10.10.0/24 <http://10.10.10.0/24> with c1=10.10.10.11 ...
c8=10.10.10.18 ... on a dedicated switch all by themselves.
To make use of the full bandwith of both LANs, I had thought of
playing with /etc/hosts files to switch networks for each machine
with a higher address than the host in question. Think of it as
one LAN flows only uphill, the other flows only downhill. So on
machine Cloud4, for example, the hosts file would appear as...
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
10.10.0.8 macpro.hoodel.com <http://macpro.hoodel.com> macpro

Question: How many services would this approach break?
