ming95 updated SPARK-42594:
---
Description:
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.
