Jimmy Xiang commented on HIVE-10956:
------------------------------------
I have a new patch in testing now. The code is changed. As to GC, it is not
reliable. We don't know when it is invoked. When the session is closed, it
should be the right time to close the HMS connection too.
> HS2 leaks HMS connections

> 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.
