>             Project: ZooKeeper
>          Issue Type: Bug
>    Affects Versions: 3.6.3
>            Reporter: May
>            Priority: Major
>
> # client connects to node ZK1;
> # client creates an ephemeral znode "/eph"
> # client closes the session;
> # ZK1 crashes before sending closing session request  to leader
> # the ephemeral znode "/eph" leaves in the cluster
> Since ZK1 is down, the cluster should clean up sessions that connect to ZK1.
