> I guess the {{hive.spark.}} configs were initially intended for the RSC.
> Therefore when they're changed, we'll re-create the session for them to take
> effect. There're some configs not related to RSC that also start with
> {{hive.spark.}}. We'd better rename them so that we don't unnecessarily
> re-create sessions, which is usually time consuming.
