Hi, everyone,

We are now trying building a hadoop cluster. Every node (namenode and
datanodes) in the cluster has two interfaces: eth0 connects to a inner lan
which only serves for applications within the lan, while eth1 connects to a
public network.

eth0: 10.0.0.0/16
eth1: 192.168.4.0/24

After starting hadoop, we found it only listening on the interface which IP
address is associated to the hostname in the file core-site.xml. As a
result, we want to make it listen on both the two interfaces.

Anyone could give some help ? Thank you !

once i didn't know software is not free, but found it days later; now i
realize that it's indeed free.

Hadoop uses DNS lookup to associate IP with hostname.

It would be better if you follow the rack concept and have a ToR (Top of
Rack) switch which allows for port bonding.

See HBASE-2502 also.
