ulysses you created SPARK-30201:
-----------------------------------

             Summary: HiveOutputWriter standardOI should use ObjectInspectorCopyOption.DEFAULT
                 Key: SPARK-30201
                 URL: https://issues.apache.org/jira/browse/SPARK-30201
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: ulysses you


Now spark use `ObjectInspectorCopyOption.JAVA` as oi option which will convert any string
to UTF-8 string. When write non UTF-8 code data, then `EFBFBD` will appear.
We should use `ObjectInspectorCopyOption.DEFAULT` to support pass the bytes.

Here is the way to reproduce:
1. make a file contains 16 radix 'AABBCC' which is not the UTF-8 code.
2. create table test1 (c string) location '$file_path';
3. select hex(c) from test1; // AABBCC
4. craete table test2 (c string) as select c from test1;
5. select hex(c) from test2; // EFBFBDEFBFBDEFBFBD
