> libhdfs++: Reimplement Status object as a normal struct

>
> hdfs::Status is doing all sorts of reinterpret casts on a block of memory
> referenced by a char *. Using a char *, casting to a wider type, and
> dereferencing can cause fun alignment issues.
> As far as I can tell that data layout in status can be boiled down to:
> {code}
> class Status {
> int code;
> std::string msg;
> }
> {code}
> This avoids doing manual memcopies in the copy ctor and delete[]s in the
> dtor. It will also get rid of boilerplate null checks and casts.
