Bennie Schut commented on HIVE-1482:
------------------------------------
The proxy sounds like an interesting approach. It will probably synchronize a
little more then we need but it's a lot safer and the normal use case is
calling the methods sequentially anyway so not much loss there.
Doing a little mutithreading test is a good idea. I've had some HIVE_PLAN
exceptions in the past (different jira) which would probably also become
visible then. I'll have a look.
Thanks.
