Over at GridEngine.info
they found a link on DanT's Sun blog
that has a sweet tutorial on setting up Hadoop using SGE's parallel environments
with loose integration.
Here we are relying on master node to start othe daemons ( [rs]sh the machine and start daemons) and distribute jobs , and we donot have control on the TaskTracker threads. This way of setting a pe in Grid Engine is called loose-integration
With some more effort one could also achieve a tighter integration wherein the task of starting daemons and tasks on other slaves could be done by SGE. But this would require further understanding of Hadoop internals.
