Hi everyone,

I know this is the common mistake to not specify the class adress while
trying to run a jar, however,
although I specified, I am still getting the ClassNotFound exception.

What may be the reason for it? I have been struggling for this problem more
than a 2 days.
I just wrote different MapReduce application for some anlaysis. I got this
problem.

To check, is there something wrong with my system, i tried to run WordCount
example.
When I just run hadoop-examples wordcount, it is working fine.

But when I add just "package org.myorg;" command at the beginning, it
doesnot work.

Here is what I have done so far
*************************************************************************
1. I just copied wordcount code from the apaches own examples source code
and I just changed package decleration as "package org.myorg;"
**************************************************************************
2. Then I tried to run that command:
 *************************************************************************
"hadoop jar wordcount_19_02.jar org.myorg.WordCount
/home/hadoop/project/hadoop-data/NetFlow 19_02_wordcount.output"
*************************************************************************
3. I got following error:
**************************************************************************
[hadoop@ADUAE042-LAP-V project]$ hadoop jar wordcount_19_02.jar
org.myorg.WordCount /home/hadoop/project/hadoop-data/NetFlow

So as you see, package decleration is fine but I am really helpless, I
googled but they are all saying samething you should specify the package
hierarchy of your main class. I did know it already I am specifying but
doesn't work.

I would be much obliged to anyone helped me

Regards,

Have you used the Api setJarByClass in your main program?

Thanks Hemanth for your reply.

Unfortunately, I used in mycode. Also to control my system I tried to run
Wordcount example of apache.hadoop itself by just changing the package
info, this one also did not work

Thank you very much.
When i tried with wordcount_classes.org.myorg.WordCount, I am getting the
following error:

I am not sure if that will actually work, because the class is defined to
be in the org.myorg package. I suggest you repackage to reflect the right
package structure.

Also, the error you are getting seems to indicate that you aphave compiled
using Jdk 7. Note that some versions of Hadoop are supported only on Jdk 6.
Which version of Hadoop are you using.

Thanks
Hemanth

Thats because the error is not related to the packaging. As mentioned in my
last mail, downgrade the java version used for compiling your code from Jdk
7 to Jdk 6. If you are using an IDE, it will have an option to set the
target compilation version. Google will help.
