Setting up another machine as secondary node

[Rakhi Khatwani]

Hi,
     I wanna set up a cluster of 5 nodes in such a way that
node1 - master
node2 - secondary namenode
node3 - slave
node4 - slave
node5 - slave


How do we go about that?
there is no property in hadoop-env where i can set the ip-address for
secondary name node.

if i set node-1 and node-2 in masters, and when we start dfs, in both the
m/cs, the namenode n secondary namenode processes r present. but i think
only node1 is active.
n my namenode fail over operation fails.

ny suggesstions?

Regards,
Rakhi
