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.
