> 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}
