See http://incubator.apache.org/pig/. Hope that helps. Not sure how joins
could be done in Hadoop.

Hi,
I'm currently looking into how to better scale the performance of our
calculations involving large sets of financial data. It is currently using
a series of Oracle SQL statements to perform the calculations. It seems to
me that the MapReduce algorithm may work in this scenario. However, I
believe would need to perform some denormalization of data in order for this
to work. Do I have to? Or is there a good way to implement joins within
the Hadoop framework efficiently?
Thanks,
Chuck
