>             Project: Hive
>          Issue Type: Improvement
>          Components: Security
>    Affects Versions: 3.0.0

> 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.
