James Clampffer commented on HDFS-8766:
---------------------------------------

Thanks for the review Haohui!

Good catch on the "using namespace" in the header, that must have ended up 
there while I was splitting the files apart.  I'll fix that, the comment issue, 
and go back to using shared_ptrs to the promises to fix the race condition 
similar to your fix on the old github branch.

> 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.
