-------------------------------------
Summary: Zookeeper 3.5.7 not creating snapshot
Key: ZOOKEEPER-3781
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3781
Project: ZooKeeper
Issue Type: Bug
Reporter: Weichu Liu
Attachments: zk_no_snapshot.zip
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.

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.
