> Are you saying that if a field in the Hive table is an array and there are
two records with the same array value, this bug will be triggered？
Yes, if nonull records in a rowBatch is same，like：
```
['欧元'],null,['欧元']
```
Here are my testing steps:
1. sql:
```sql
CREATE TABLE `test.orc_array_2`(
`finance_currency` array<string>
) PARTITIONED BY (`dt` string) STORED AS ORC;
insert into test.orc_array_2 partition (dt="2025-01-06") values
(array('欧元')),(array('欧元'));
```
2. copy file `/user/hive/warehouse/test/orc_array_2/dt=2025-01-06/000000_0`
into the project `connector-file-base/src/test/resources/000000_0` , change
testOrcRead()
3. change `OrcReadStrategyTest.testOrcRead()` content "/test.orc" into
"/000000_0", the error will happen.
