One way (a bit hacky) is to have the 2nd operator monitor an empty directory. Then, when the 1st is done reading, it sends a control tuple to a "file-link" operator; that operator creates symbolic links from the directory monitored by the 2nd operator to the actual input files. That should then trigger the 2nd input operator to do its thing.
