Summary: To further distinguish the corruption cases were caused by storage media or in memory states when writing it, add a paranoid check after writing the file to iterate all the rows. Test Plan: Add a new unit test for it Reviewers: rven, igor Subscribers: leveldb, dhruba Differential Revision: https://reviews.facebook.net/D37335
