> Libhdfs++ can work itself into a state where it needs to shutdown, in this
> case due to config issues, and during deconstruction attempts to call
> shutdown() and close() on an asio::tcp::socket that was never opened. This
> causes asio to throw a std::system_error which ends up terminating the
> process. See attached stack for details.
> The fix is just to make sure the rpc_connection is actually connected before
> attempting to close it.
> {code}
