Jobs submitted from slave nodes?

Hi,
Can M/R jobs be submitted from a slavenode(datanode) i.e. not a namenode in
a hadoop cluster?
If no, what changes are to be done?

Yes. Basically, if a machine can connect to the JT/NN, it can try to
submit a job. The programs merely have to point at the right cluster
locations during submission.
