>             Project: ZooKeeper
>          Issue Type: Bug
>    Affects Versions: 3.6.3
>            Reporter: gaoyu
>            Priority: Major
>
> I am using the latest stable release 3.6.3. Here is the minimal workload to reproduce the bug:
>  # There is a zookeeper cluster with three nodes: node1, node2 and node3;
>  # Start the cluster from scratch;
>  # node2 becomes the leader;
>  # Stop node2;
>  # node3 becomes the new leader;
>  # Client requests to create a znode;
>  # Restart node2;
>  # node2 receives SNAP from node3;
>  # node2 receives the NEWLEADER message from node3;
>  # node2 takes current snapshot;
>  # node2 crashes before writing to the current epoch file;
>  # Restart node2 but it fails since "Unable to load database on disk".
