Sergey Shelukhin updated HIVE-17431:
------------------------------------
Description:
The configuration is only set when opening the session; that seems unnecessary
- it could be set in the ctor and made final. E.g. when updating the session
and localizing new resources we may theoretically open the session with a new
config, but we don't update the config and only update the files if the session
is already open, which seems to imply that it's ok to not update the config.
In most cases, the session is opened only once or reopened without intending to
change the config (e.g. if it times out).
