Minor Description
In many of the example scripts, a directory in /tmp (e.g. /tmp/mahout-work-dir) is created for use as temporary scratch space, such as to store data files that are downloaded.
In a number of HPC environments, /tmp may not exist or /tmp may be very small b/c local disk drives don't exist. It'd be convenient to be able to specify an alternate directory to use as scratch space.
