------------------------------------------
Are you actually running it out of the build directory? If so, that's the problem.

> My Hadoop installation is having trouble loading the native code library. It appears from the log below that java.library.path is missing the basedir in its path. The libraries are built, and present in the directory shown below (relative to hadoop-common directory). Instead of seeing:
> /build/native/Linux-amd64-64/lib
> I would expect to see:
> /path/to/hadoop-common/build/native/Linux-amd64-64/lib
> I'm working in branch-0.22.
