> Key: ZOOKEEPER-3682
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3682
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Reporter: Jie Huang
> Priority: Minor

> Time Spent: 50m
> Remaining Estimate: 0h
>
> ZK keeps accepting new connections while it's being shut down then immediately close them when it finds out that the ZK server is not running. It's not a big deal before SSL is enabled since creating TCP connections is relatively cheap.
>
> With SSL being widely enabled, creating SSL connections involves handshake that takes non-trivial CPU time, which is wasted since the connections are closed right after.
>
> This JIRA is going to stop initializing TLS handshake if the zkServer is not serving to save resources.
