Rui Li commented on HIVE-17964:
-------------------------------
At the moment, only two configures need re-creating session:
{noformat}
hive.spark.optimize.shuffle.serde
hive.spark.client.future.timeout
{noformat}
Other {{hive.spark.}} configs either don't require a new session, or are
already immutable at runtime.
BTW, I missed {{hive.spark.client.rpc.sasl.mechanisms}} in HIVE-16876, so I
made it immutable here.
> HoS: some spark configs doesn't require re-creating a session

> 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.
