I removed the entry 127.0.1.1 in /etc/hosts on all the nodes and the cluster is working fine now. Thank you very much for your help.

I did go through the 6 steps listed at the link and telnet to port 45965 is failing. Netstat -a shows nothing is listing on port 45965.
That's a high number - I wonder if it's something transient that didn't start.
I worry about the 127.0.1.1 number in the hostname -try editing /etc/hosts to 127.0.0.1 to see if that helps; it could just be some listening on a different port
We can run hadoop 1.0.3 version without any issues on this cluster and I am new to 2.0.0 version. I followed the document http://hadoop.apache.org/common/docs/r2.0.0-alpha/hadoop-yarn/hadoop-yarn-site/ClusterSetup.html to setup the config files. Is there any other good document that describes how to set up version 2.0.0.

I am trying to setup a small cluster using hadoop 2.0.0 and using PI example to validate the setup. When I have 1 master and 1 slave the example works fine. I am getting exceptions with the PI example when additional slave nodes are added to the cluster. The syslogs for failed tasks are as follows. Any ideas why this is happening.
