Aihua Xu commented on HIVE-13194:
---------------------------------
[~sershe] The HMSClient inside Hive object right now is thread-safe after
HIVE-10956. So what I think is, when the query starts to compile, we create a
Hive object for it and then it will not change during its life time. Seems we
can remove the threadlocal for Hive object. Do you see any drawback on that? I
feel we can simplify the logic on this.
Can you elaborate what are we trying to do in this patch?
> Hive object is not thread safe, is shared via a threadlocal and thus should
> not be shared via session - part 2

> Session has session Hive object stored in a field. Given that Hive object is
> not thread safe and is also taken from a threadlocal to start with, that is
> not a good idea.
