> 1. Spark would save view schema as tabel param. 
> 2. Spark will make tabel param as output schema when select the view .
> 3. Hive will not update tabel param when runing `create or replace view` to update the view.
> !image-2023-02-27-13-31-20-420.png!
> So when hive and spark are mixed and update the view, spark may ignore some col.
> To reproduce this issue:
> 1. running in spark
> ```
> create table test_spark (id string);
> create view test_spark_view as select id from test_spark;
> ```
> 2. running in hive
> ```
> create or replace view test_spark_view as select id , "test" as new_id from test_spark;
> ```
> 3. We can see spark will ignore `test_spark_view#new_id` when select test_spark_view using spark. But hive can read it.
> I'm not sure if this is a feature of spark.
