Hi, once you have started the jobtracker+namenode on your cluster, you can launch a job from any node of the cluster.
AFAIK, to submit multiple jobs you need to do that yourself either: - by writing a bash script to launch several jobs.jar one after the other - by bundling several jobs in a single job.jar (calling API:: JobClient.runjob( job ) repeatdly for each job in jobs ), for this you have to create a new instance of JobClient for each job.
