Thawan Kooburat commented on ZOOKEEPER-1813:
--------------------------------------------
I believe this is similar issue as ZOOKEEPER-1573. In that case, I found that
it is a false positive. If the check is disable, the result after snapshot
restore is still a valid state of the system. I don't quite follow your
example but it seem to be similar that we can ignore the failure right?
Anyway the work around is to actually remove snapshot and txnlog for a given
server.
