public void testReplayWorksThoughLotsOfFlushing()
                                         throws IOException

HBASE-12782 ITBLL fails for me if generator does anything but 5M per maptask. Create a region. Close it. Then copy into place a file to replay, one that is bigger than configured flush size so we bring on lots of flushes. Then reopen and confirm all edits made it in.

Throws:

IOException

                                                throws IOException
