> Currently we do the following to load native libraries:
> 1) Ask parent class loader (normally it is app class loader) to load {{org.apache.hadoop.util.NativeCodeLoader}}
class. It will force loading of relevant Hadoop native libraries.
> 2) Then hack into parent class loader internals, find loaded library, and wire it up
to current classloader.
> This approach will not work any more because parent classloader normally will not have
Hadoop in classpath.
> We should provide alternative solution.
