Hadoop "Retrying connect to server" issue
===

I am trying to run hadoop with 2 machines with one as master and other as slave.

Getting the below error in the slave's datanode and tasktracker log files, when I startup mapred and dfs from the master:

INFO org.apache.hadoop.ipc.Client: Retrying connect to server

Am not able to access localhost:50060 (Tasktracker url) on the slaves. Also from  the command "sudo netstat -plten | grep java" , I can't see hadoop listening for the tasktraker. 

I too have the same problem, tried some of the workaround provided here but to no avail. Help appreciated.
