> libhadoop calls {{dlopen}} to load {{libsnappy.so}} and {{libz.so}}.  These libraries
can be bundled in the {{$HADOOP_ROOT/lib/native}} directory.  For example, the {{-Dbundle.snappy}}
build option copies {{libsnappy.so}} to this directory.  However, snappy can't be loaded from
this directory unless {{LD_LIBRARY_PATH}} is set to include this directory.
> Can we make this configuration "just work" without needing to rely on {{LD_LIBRARY_PATH}}?
