Cheng Lian commented on SPARK-4037:
-----------------------------------
This is a regression of SPARK-2814, added in SPARK-3729.
One solution is let HiveContext always reuse SessionState started within the
same thread, if there's none, create a new one. In this way, we don't need to
override the SessionState field in HiveThriftServer2, thus eliminate this issue.
