James Clampffer updated HDFS-8766:
----------------------------------
Attachment: HDFS-8766.HDFS-8707.000.patch
Some notes on first patch:
-Just enough done to open, read, and close a file. More patches are coming but
I'd like some early feedback.
-This includes the patch from HDFS-9108
-Two hdfs.h files in the same project will likely lead to issues, I'd like to
keep compatibility/hdfs.h named as it is so people don't have to change their
includes to link
Thoughts on more appropriate errnos would be appreciated.
> Implement a libhdfs(3) compatible API

>
> 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.
