Kobe, Paolo, At the moment IGFS has no adapters to interact with "regular" file systems without Hadoop. Note that Hadoop comes with LocalFileSystem [1] class which delegates to OS file system. Probably you can give it a chance and check whether it meets your requirements.
Some time ago there was a discussion to implement native IGFS -> OS adapter [2], but no final decisions were made. As were are seing growing interest to this feature probably we should resume this thread.
