you can follow this tutorial:

http://hadoop-tutorial.blogspot.com/2010/11/running-hadoop-in-distributed-mode.html
http://cloudera-tutorial.blogspot.com/2010/11/running-cloudera-in-distributed-mode.html
also, before running any job please ensure all the required processes are
running on the correct node
like on master:
Namenode, jobtracker, secondarynamenode(if you are not running secondary
name node on another system)

on slave:
datanode, tasktracker
