-------------------------------------------
There is one thing I missed in my earlier review that has me *slightly*
concerned:

This basically means that hadoop-common's native MUST always be compiled prior
to compiling this code. It really seems like a gotcha waiting to surprise
someone. It definitely means that Yetus' hadoop driver will likely fail any
builds of this code until it's told about that requirement.

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some
> cases. Also, on some alternate, non-x86, non-ARM architectures the generated
> code is incorrect. Thanks to Steve Loughran and Edward Nevill for finding
> this.
