The build was successful with those "warning".
I could not run a test case from this website:

Here are my run with the error:

Hm, OK something sounds wrong with your directory structure, given the
warnings. I assumed this was changed. It could be that the .tar.gz distribution
isn't quite correctly set up for building from source.
The compilation here is nothing to do with Hadoop. You show a successful build;
what's the part that fails?
