Debugging DFS and MapReduce through Eclipse

[Dennis Kubes]

Has anyone been able to successfully debug DFS and MapReduce servers 
running though eclipse.  I can get all the servers started and can run 
MapReduce tasks inside of eclipse but I am getting both classpath errors 
and debugging stalls.

I am just curious what kinds of setups people have for doing large scale 
development of DFS and MapReduce?
