You said the folder may_24 might be there -- but you need to provide the
full name of a class, not just a package. A folder denotes a package. So is
there a may_24.class file? Or is the main() method in some may_24/Foo.class?
If so, then you need to run bin/hadoop jar hadoop_out_degree.jar may_24.Foo
(args...)
Creating the jar using Sun's jar program should automatically insert the
necessary manifest.
What does 'jar tf hadoop_out_degree.jar' return?

It looks like that you miss some packages (xxx.xxx.xx.may_24). Check
the package names.
If not, try to run the hadoop_out_degree.jar with main class.

Hello everyone,
I am getting some issues when compiling a map-reduce program similar to
wordcount example.
I followed the instruction in the tutorial and succeeded to compile a jar
file.
The problem won't appear until I run it as below:
had...@lobo:/osr/Projects/anansi/mrjobs/src$
/osr/Projects/anansi/hadoop/bin/hadoop jar ./hadoop_out_degree.jar may_24
outout1/

The folder 'may_24' is definitely there, I am not sure whether I missing
something when compile, do I have to add manifest file in the class folders
?
also I am confused about the error info. Could anyone give me some idea
?
Thanks in advance,
