-----------------------------------
Assignee: Laszlo Bodor
> Separate Hive Security from SessionState
> ----------------------------------------
>
> Key: HIVE-20053
> URL: https://issues.apache.org/jira/browse/HIVE-20053
> Project: Hive
> Issue Type: Improvement
> Components: Security
> Affects Versions: 3.0.0
> Reporter: Aihua Xu
> Assignee: Laszlo Bodor
> Priority: Major
>
> Right now we have Hive security classes associated with SessionState. When
> HiveServer2 starts, the service session will initialize it and later each
> session will need to reinitialize. Since such security configuration is on
> service level, we should move security info out out SessionState and make it
> Singleton so we can initialize it once.
> And also, since SessionState.setupAuth() - to setup authentication and
> authorization is not synchronized, we could run into concurrency issue if
> queries or meta operations are run within same session.
