Qi Chen 124516c1ea [Fix](orc-reader) Fix Wrong data type for column error when column order in hive table is not same in orc file schema. (#21306)
`Wrong data type for column` error when column order in hive table is not same in orc file schema.

The root cause is in order to handle the following case:

The table in orc format of Hive 1.x may encounter system column names such as `_col0`, `_col1`, `_col2`... in the underlying orc file schema, which need to use the column names in the hive table for mapping.

### Solution
Currently fix this issue by handling the following case by specifying hive version to 1.x.x in the hive catalog configuration.

```sql
CREATE CATALOG hive PROPERTIES (
    'hive.version' = '1.x.x'
);
```
