Subject Re: Packaging multiple map reduce jobs into one Jar

Yes you can do this.
You can have multiple main in your jar, so you can run,
            hadoop jar jarname.jar packagename.classname arguments

            for eg: hadoop jar myJar.jar my.testapp.code1.MyMain1 arg1 arg2
                      hadoop jar myJar.jar my.testapp.code2.MyMain2 arg1
arg2
