Hi Stephen et al.,
I would take advantage of the Hadoop plug-in for Eclipse to handle the
mundane aspects of putting together your job and running it on the cluster.
With respect to gentler introductions on application development, you
might want to take a look at the following:
http://www.umiacs.umd.edu/~jimmylin/cloud9/umd-hadoop-dist/cloud9-docs/index.html
Cloud9 is a MapReduce library primarily intended for teaching, which I
use in my cloud computing course (going on right now). The associated
tutorials might help you get started. Thus far it's worked well with U.
Maryland grads and undergrads, but I'd appreciate additional feedback.
Incidentally, I will be talking at the Hadoop summit next week, so if
anyone else on the list will be there, I look forward to meeting everyone!

Hello,
I am working on developing my first hadoop app from scratch. It is a
Monte-Carlo simulation, and I am using the PiEstimator code from the
examples as a reference. I believe I have what I want in a .java file.
However, I couldn't find any documentation on how to make that .java
file into a .jar that I could run, and I haven't found much
documentation that is hadoop specific.
Is it basically javac MyApp.java
jar -cf MyApp
or something to that effect, or is there more to it?
Thanks! Sorry for the newbie question.
