Ivan A. Veselovsky commented on HADOOP-9205:
--------------------------------------------
Hi, Thomas,
can you please provide more detail on your environment: what OS did you use?
I experimented on "CentOS release 6.3 (Final)" and "Ubuntu precise (12.04.1
LTS)".
BTW, the problem with missing symlink libhadoop.so -> libhadoop.so.1.0.0 can be
avoided in you install "cmake" utility of version >= 2.8. On CentOS systems
this version is installed as a separate package named "cmake28", and
corresponding executable is /usr/bin/cmake28. We create symlink cmake ->
cmake28, and after that the problem goes away.

> Currently the path to native libraries is passed to unit tests via
> environment variable LD_LIBRARTY_PATH. This is okay for Java6, but does not
> work for Java7, since Java7 ignores this environment variable.
> So, to run the tests with native implementation on Java7 one needs to pass
> the paths to native libs via -Djava.library.path system property rather than
> the LD_LIBRARY_PATH env variable.
> The suggested patch fixes the problem via setting the paths to native libs
> using both LD_LIBRARY_PATH and -Djava.library.path property. This way the
> tests work equally on both Java6 and Java7.
