> FileSystem's getFileCacheHints should be replaced with something more useful. I'd suggest replacing getFileCacheHints with a new method:
> {code}
> BlockLocation[] getFileLocations(Path file, long offset, long range) throws IOException;
> {code}
> and adding
> {code}
> class BlockLocation implements Writable {
>   String[] getHosts();
>   long getOffset();
>   long getLength();
> }
> {code}
