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

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

It cannot find your job jar file. 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).

Hi Group,


I was having trouble getting through an example Hadoop program. I have
searched the mailing list but could not find any thing useful. Below is the
issue:


1) Executed below command to submit a job to Hadoop:

 /hadoop-0.18.3/bin/hadoop jar -libjars AggregateWordCount.jar
org.apache.hadoop.examples.AggregateWordCount words/*
aggregatewordcount_output 2 textinputformat


2) Following is the error:

java.io.IOException: Error opening job jar:
org.apache.hadoop.examples.AggregateWordCount

       at org.apache.hadoop.util.RunJar.main(RunJar.java:90)

       at org.apache.hadoop.mapred.JobShell.main(JobShell.java:68)

       ... 4 more


Please advice.
