>             Fix For: HADOOP-10388
> We should avoid exposing all the symbols of libhdfs-core.so and libyarn-core.so.  Otherwise,
we they conflict with symbols used in the applications using the libraries.  This can be done
with gcc's symbol visibility directives.
> Also, we should probably include libuv and libprotobuf-c statically into our libraries,
since most distributions don't yet include these libraries, and we don't want to have version
issues there.
