Sergey Shelukhin commented on HIVE-10956:
-----------------------------------------
Well it's a tradeoff... the leak will definitely be fixed by finalizer. I don't
think we have the pressure to close the connection ASAP. It's a much simpler
fix than the attached patch that reimplements threadlocal. As much as I dislike
Java, and GC in particular I'd rather not do that.
Other patch welcome :)

> HS2 uses threadlocal to cache HMS client in class Hive. When the thread is
> dead, the HMS client is not closed. So the connection to the HMS is leaked.
