The file will not appear to exist at all until the writer is done.

If you jus tlist the directory, you will see the file appear.

OR...

You could use an out-of-band signal from the writer to the reader.

You don't have to use Hadoop for everything.  It is only intended to do the
things that you can't do otherwise, not replace things you can already do.
