Richard and Ramon Yes, I think there should be a way as you see there is a class named JobClient in org.apache.hadoop.mapred which is basically invoked from commandline , if you open hadoop shell script my point will be clearer. Also I suggest you take a look at oozie there using java apis you can submit jobs to Hadoop.
