> Current Hive.get(HiveConf) creates and returns a new Hive object when the ThreadLocal Hive is null or HMS config is not compatible, but does not do that when it is called in a thread which has been switched to execute a session with a different userId. It will cause the impersonation issue to HMS.
> It is related to HIVE-7890.
