Thanks for your reply Harish.
Am running this example from with in the directory containing AggregateWordCount.jar file. But even then, I have this issue. Earlier I had issue of java.lang.ClassNotFoundException: org.apache.hadoop.examples.AggregateWordCount$WordCountPlugInClass, so in some thread some one have suggested using -libjars, so I tried, but there was not great!!! I did not think it is SUCH A HARD JOB (almost 20+ hours with no success) to just run an example provided by Hadoop in its distribution!!! Thank You, Shravan Kumar. M Catalytic Software Ltd.

Make sure you run this command from the directory that has the AggregateWordCount.jar (and you can lose the -libjars flag too - you need that only if you need to specify extra jar dependencies apart from your job jar file). - Harish On Mon, Jun 22, 2009 at 3:45 PM, Shravan Mahankali <shravan.mahank...@catalytic.com> wrote: Hi Group, I was having trouble getting through an example Hadoop program.
