> Today the DataNode perform ACL check and block token verification on each
> DataNodes.
>
> This is wrong, as DataNode can diverge in state. Only leader DN should decide
> to accept a request or not. I have seen a case where the follower reject a
> request because its block token expired, but the leader accepted the request.
> State diverged.
