> 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.
