Description

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.
