Jakob Homan commented on HDFS-830:
----------------------------------
I'm not wild about checking in jars just for testing, even if it is to your
local mvn repository. That adds an extra step of cleaning them up. Instead,
how about if we have property for Ant such as -Dusejar= and provide a list of
jars to be included. I can see this making it very easy to write a script to
test up-the-line changes from common and hdfs to hdfs and mapreduce. This would
also save the time of having to copy the jars into the lib directory: build the
common jar, point hdfs to it when running tests with no extra checking in or
copying muss or fuss.
> change build.xml to look at lib's jars before ivy, to allow overwriting ivy's
> libraries.

> Currently build.xml looks first into ivy's locations ,before picking up jars

> We need to change that to allow overwriting ivy's libs with local ones, by
