can you ping each other ? make sure they are no network issues. Also make sure each other
can resolve their DNS/ip with a DNS server or adding them to the /etc/host turn iptables off
and try.

Subject: Issue while starting a NodeManager

I setup a four node VM cluster for Hadoop 2.2.0 using CentOS. On the machine ( named Monkey)
when I am starting the NodeManager I am getting the following error - 

java.net.NoRouteToHostException: No Route to Host from  
monkey/ to horse:8700 failed on socket timeout exception: 
java.net.NoRouteToHostException: No route to host; For more details 
see:  http://wiki.apache.org/hadoop/NoRouteToHost

I verified the config files and also the communication between the four nodes.
Which configuration file this error would be thrown ? Please advise.
