--------------------------------------
[~sershe]
1. Yes SessionState.get().isHiveServerQuery() is a good way to check if its in
HS2.
2. Compilation threads do get re-used across queries. Something that shouldn't
be re-used across sessions should ideally be part of objects mapped to Driver
objects lifetime.
