> Add authentication in MetaSnapshot
> ----------------------------------
>
> Key: IOTDB-601
> URL: https://issues.apache.org/jira/browse/IOTDB-601
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Core/Cluster
> Reporter: Tian Jiang
> Priority: Major
> Labels: authentication, cluster, snapshot
>
> Although AuthorPlans are supported, authentication information like users,
> roles, privileges are not concluded in the MetaSnapshot, so when meta logs
> are removed, the stale nodes will not be able to catch up with the leader.
> Authentication information can be directly added into current MetaSnapshot so
> that the receiver can recover from it without further transmission or as a
> descriptor in the MetaSnapshot through which the receiver can know where to
> pull the information.
