### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened When reading ORC files containing a struct type column, HdfsFileSource ignores the case sensitivity of internal string fields within the struct. As a result, the original content of these string fields is not correctly parsed, leading to altered or incorrect values in the output. source: "cond_keys":{'MD5': '5035eb942416f6c41ea48adabb7654de'} output: "cond_keys":{"MD5":null} sample orc file [mock_data.orc.zip](https://github.com/user-attachments/files/21679019/mock_data.orc.zip) ### SeaTunnel Version 2.3.7 ### SeaTunnel Config ```conf env { # You can set flink configuration here execution.parallelism = 1 job.mode = "BATCH" } source { LocalFile { path = "./mock_data.orc" file_format_type = "orc" result_table_name = "fake" } } sink { Http { url = "http://127.0.0.1:8080/api/print"; headers = { "Content-Type" = "application/json" } # Optional: retry configuration # retry = 3 # retry_backoff_multiplier_ms = 1000 # retry_backoff_max_ms = 10000 } } ``` ### Running Command ```shell just run with " -e local" ``` ### Error Exception ```log no error ``` ### Zeta or Flink or Spark Version local mode ### Java or Scala Version openjdk version "11.0.17" 2022-10-18 LTS OpenJDK Runtime Environment Zulu11.60+19-CA (build 11.0.17+8-LTS) OpenJDK 64-Bit Server VM Zulu11.60+19-CA (build 11.0.17+8-LTS, mixed mode) ### Screenshots <img width="263" height="18" alt="Image" src="https://github.com/user-attachments/assets/e6b33edd-f295-4054-917c-9bd10a8c769f"; /> ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
