Hi Nikhil, Appreciate your quick response on this, but the issue still continues. I believe I have covered all the pointers you have mentioned. Still I am pasting the portions of the documents so that you can verify.
1. /etc/hosts file, localhost should not be commented, and add ip address. The entry looks like the below: # localhost name resolution is handled within DNS itself. 127.0.0.1 localhost 2. core-site.xml, hdfs//localhost:port number <configuration> <property> <name>fs.default.name</name> <value>hdfs://localhost:9000</value> </property> </configuration> 3. mapred-site.xml hdfs//localhost:port number mapred.local.dir <configuration> <property> <name>mapred.job.tracker</name> <value>localhost:9001</value> </property> </configuration> 4. hdfs-site.xml 1.replication factor should be one include dfs.name.dir property dfs.data.dir property for both the property check on net <configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.name.dir</name> <value>c:/Hadoop/name</value> </property> <property> <name>dfs.data.dir</name> <value>c:/Hadoop/data</value> </property> </configuration> I am getting stuck at: 13/08/30 11:39:26 WARN mapred.JobClient: No job jar file set.

Does this ring any bells to you?
