Hi Harish, PFA the AggregateWordCount.jar file.
I was able to open this jar file using a sample Java file written with JarFile api, and this is the same api used inside org.apache.hadoop.util.RunJar class, where my jar is rejected and throwing the error!!! Also find attached the sample java file - RunJar1.java Thank You, Shravan Kumar. M Catalytic Software Ltd.

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.
