This is not true. There is an explicit hadoop2 compile check because there
are APIs that are only present in hadoop2 that will fail in a hadoop1
compile, and deprecated apis in hadoop1 that are not present in hadoop2,
and signatures that have changed subtly between and h2.

Did a patch apply use any hadoop-common or hadoop apis that aren't present
in hadoop2?
