> In theory, running the launcher job in Hadoop 2's uber mode should make the
> overall action time faster because we don't need to launch as many JVMs.
> I tested this out on a few of the examples in a VM, and it seems to save
> about 10 - 50 seconds per action. While my testing wasn't scientific and was
> only on a single VM, setting the launcher job to run in uber mode by default
> is such a trivial change and should at least not make it slower that I think
> we should do it.
