Open the firewall on each node for the other nodes.

Add these lines to /etc/sysconfig/iptables on each node replacing NODE#_IP with the corresponding IP address:

-A INPUT -s NODE1_IP -j ACCEPT
-A INPUT -s NODE2_IP -j ACCEPT
-A INPUT -s NODE3_IP -j ACCEPT

Then restart iptables: service iptables restart

This can be the problem of firewall also.Try to stop your firewall and test again. For centos 6 following command should work.

service iptables stop
