I see. I will roll it back.
> Add some limitations on code level for `SID` to avoid configuration problem
> ---------------------------------------------------------------------------
>
> Key: ZOOKEEPER-2784
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2784
> Project: ZooKeeper
> Issue Type: Improvement
> Components: quorum
> Affects Versions: 3.5.2
> Reporter: Benedict Jin
> Fix For: 3.6.0
>
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> As so far, `QuorumCnxManager#receiveConnection` cannot find out the same
> `SID` problem, then the Zookeeper cluster will start successfully. But the
> cluster is not health, and it will throw some problem like `not
> synchronized`. So, i thought we should add some limitations on code level for
> `SID` to find those configuration problem more early.
