Sijie Guo commented on BOOKKEEPER-500:
--------------------------------------
the users of BOOKKEEPER heavily reply on the correctness of fencing, like
Hedwig replies on BOOKKEEPER fencing to provide right sequence id, NameNode of
HDFS would also need it too. so if the bug affects the correctness of fencing,
it should be resolve in latest release. so I think it is a blocker.
> Fencing doesn't work when restarting bookies.

> Currently we just record fence state in memory. If the bookies are restarted,
> all fence states are gone. It would break the correctness that we guarantee
> about fencing.
> We should record the fence state in the file info to make it persistent.
> A test case added to produce this issue.
