> Hi,
> In our deployment, we are using zookeepers as Kafka quorum.
> Recently we upgraded Zookeeper from 3.4.14 to 3.5.7.
> During the upgrade, we enabled snapshot.trust.empty and removed it after.
> However, about 25% of zookeepers (all on 3.5.7) are not creating snapshot
> files, so they keep crashing on reboot with ERROR.
> {noformat}
> ERROR [main:QuorumPeer@937] - Unable to load database on disk
> <http://java.io|java.io>.IOException: No snapshot found, but there are log
> entries. Something is broken!
> {noformat}
> Nothing suspecious did I find from the zookeeper log.
> I managed to reproduce the issue with the data from our servers, I put them
> in the attachment.
