[jira] [Created] (HIVE-20053) Separate Hive Security from SessionState

Aihua Xu created HIVE-20053:
-------------------------------

             Summary: 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


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 it. 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.
