LinuxQuestions.org - Routing Problem - Multi-Homed Redhat Servers.

Hi,

I have just created a cluster of 7 servers running Hadoop / Hbase. As Hbase can very 'chatty' and sometimes have a need to transfer large volumes of between other servers in the cluster I multi-homed these 7 servers. The Hbase communicates with other servers in the cluster using Eth1 on a 10.10.10.x private network using a dedicated switch. This is to avoid possible saturation of our 'general use' network 172.x.x.x.

The other NIC on these 7 servers, Eth0 - has a static IP and is connected to our companies regular 172.x.x.x network. We will obviously need to reach the cluster servers from other Linux hosts (running Java) and perhaps some Windows systems. I don't know exactly how Java communicates with Hbase, but I think it will use ip/port ( 10.10.10.x:5555 ).

I need some kind routing on each of the 7 cluster servers to enable the 172..x.x.x systems reach Hbase.

Any suggestions would be much appreciated.

Here is an ifconfig -a output:
