Vaibhav Gumashta commented on HIVE-10876:
-----------------------------------------

This could also be potentially something that we be worked on in the proposed 2.0 branch (along
with replacing CLI impl with Beeline+embedded HS2).

> It appears that the Driver and SessionState abstractions are better served in HiveServer2
by moving the state for a query to the Operation abstraction and the state of a client session
to HiveSession. Currently, the state is mixed into Driver and SessionState which were abstractions
from the CLI/HiveServer1 world. It would have made working on HIVE-4239 much easier.
