+ fs = f;
+ stat->set_value(s);

{code}
It might make sense to rename the {{libhdfspp/hdfs.h}} to
{{libhdfspp/libhdfspp.h}}. It is also beneficial to change the way how the
{{FileSystem}} works to only make the connection when calling {{Connect()}}.
However, I think both of them can be addressed in follow-up jiras.

> Add a synchronous API that is compatible with the hdfs.h header used in
> libhdfs and libhdfs3. This will make it possible for projects using
> libhdfs/libhdfs3 to relink against libhdfspp with minimal changes.
> This also provides a pure C interface that can be linked against projects
> that aren't built in C++11 mode for various reasons but use the same
> compiler. It also allows many other programming languages to access
> libhdfspp through builtin FFI interfaces.
> The libhdfs API is very similar to the posix file API which makes it easier
> for programs built using posix filesystem calls to be modified to access HDFS.
