Hi ,

1. Make sure Name Node & Job Tracker processes are running or not.

  You can verify them using "Jps" command
2. If you use /hadoop/bin/start-dfs.sh it will start only NameNode & Data
Node and not Job Tracker.
To run Job Tracker you need use "start-all.sh" instead of "start-dfs.sh"

3. Verifying Namenodes & Job Trackers running through urls.

Name Node: http://localhost:50070
Job Tracker: http://localhost:50030

4. Verify the configuration settings @ hadoop/conf/*.xml
 Make sure you define Name node details in the "core-site.xml" and Job
tracker details in "mapred-site.xml"



Thanks,
Murali
