Charles Xie updated BOOKKEEPER-815:
-----------------------------------
Attachment: BOOKKEEPER-815.patch
The problem is when a file info is evicted from ledger cache, the bookie
forgets to flush header of the file info which cause the fence bit lost.
The fix is pretty easy. Added a test case to reproduce this behavior.
