Closes#6766 from vanzin/SPARK-6511 and squashes the following commits:
49f0f67 [Marcelo Vanzin] [SPARK-6511] [docs] Fix example command in hadoop-provided docs.
This provides preliminary documentation pointing out how to use the
Hadoop free builds. I am hoping over time this list can grow to
include most of the popular Hadoop distributions.
Getting more people using these builds will help us long term reduce
the number of binaries we build.
