Colin Patrick McCabe commented on HADOOP-11505:
-----------------------------------------------
I have to confess that I also always build from the project root, since I got
tired of debugging misbuilds caused by running maven inside subproject
directories. I never saw the specific error about classes being private that
you are seeing-- my only guess is that you are somehow pulling the wrong
version of the classes-- perhaps it is a SNAPSHOT dependency?
I also noticed that hadoop-common is doing a lot of unnecessary work-- I think
you're absolutely right that a lot of things are being re-generated that don't
need to be inside hadoop-common. It would be a great service to everyone if
this time could be reduced.

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some
