James Clampffer updated HDFS-8766:
----------------------------------
Attachment: HDFS-8766.HDFS-8707.005.patch
Added basic error checking tests in gmock. They use the code from hdfs.cc to
check the status determine if a read failure should return 0 for resource
unavailable or -1 for all other errors.
> 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.
