Hi,

When I'm running an hadoop example:
$ bin/hadoop jar build/hadoop-0.20.2-dev-examples.jar wordcount gutenberg
gutenberg-output

I've noticed that it's created a job.jar file with classes of the
hadoop-0.20.2-dev-examples jar. Why job.jar is created?

In the "Hadoop-Definitive Guide" book, it exists several examples that use
the job.jar. For example:
$ hadoop jar job.jar v3.MaxTemperatureDriver -conf conf/hadoop-cluster.xml
input/ncdc/all max-temp

Is it possible to create a job.jar file in the bash command line?


PS:
I've put some posts in the MR mailing list that weren't answered. These
posts can be viewed by other users?


Regards
-- 
Pedro
