hbgstc123 opened a new issue, #9688:
URL: https://github.com/apache/hudi/issues/9688
**Describe the problem you faced**
if I create a view with spark sql:
```sql
create view view_a as
select * from hudi_table_a
```
the read view_a with flink hoodie catalog will throw error caused by schema
mismatch, because flink catalog will not include hudi meta fields, but view_a
include meta fields.
So shall we unified behavior by including meta fields when use flink to read
hudi table with HoodieHiveCatalog?
**To Reproduce**
Steps to reproduce the behavior:
1.create view with spark use sql DDL like "create view xxx as select * from
hudi_table"
2.flink read view xxx with HoodieHiveCatalog
**Expected behavior**
A clear and concise description of what you expected to happen.
**Environment Description**
* Hudi version : latest
* Spark version : 3.1
**Additional context**
**Stacktrace**
