> In HADOOP-7714, we determined that using fadvise inside of the MapReduce
> shuffle can yield very good performance improvements. But many parts of the
> shuffle are FileSystem-agnostic and thus operate on FSDataInputStreams and
> RawLocalFileSystems. This JIRA is to figure out how to allow
> RawLocalFileSystem to expose its FileDescriptor object without unnecessarily
> polluting the public APIs.
