George, I haven't used the Hadoop perspective in Eclipse so I can't help with that specifically but map/reduce is a batch process (and can be long running). In my experience, I've written servlets that write to HDFS and then have a background process perform the map/reduce. They can both run in background under Eclipse but are not tightly coupled.

Now I have both hadoop perspective and java ee perspective. I wonder if I can have these two together, that I can use the mapper and producers in my servlet. Anyone has experience about this? I will appreciate it. George
