Hi Farrokh, Moving this to cdh-u...@cloudera.org as it is a CDH4 specific question. I've bcc'd hdfs-user@ and cc'd you in case you aren't subscribed to cdh-user (http://groups.google.com/a/cloudera.org/group/cdh-user/).
What OS packages of CDH4 are you using? And how exactly are you attempting to start your DN? Do you simply do "sudo service hadoop-hdfs-datanode start" and get this?
