programming java ee and hadoop at the same time
Hello users,
I am trying to program a hadoop powered web application with Eclipse as IDE.
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.

I've discussed this recently, having a good binding from webapps to the
back end, where the back end consists of HDFS, MapReduce queues, and
things round them
https://svn.apache.org/repos/asf/labs/clouds/src/doc/apache_cloud_computing_edition_oxford.odp
If people are willing to help with this, we have an apache "lab"
project, Apache Clouds, ready for you code, tests and ideas

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.
