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.
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.
