…ookincubator#11963)

Summary:
Although we support JVM libhdfs, Gluten's internal benchmark still uses Libhdfs3. We encountered a 'File Not Found' exception when reading the HDFS path with libhdfs3.

```
Reason: Unable to get file path info for file: hdfs://b49691a74b48.jf.intel.com:8020/tpch_sf3000/lineitem/part-00281-3761d71a-87c6-4341-8f1c-db804f904130-c000.snappy.parquet. got error: FileNotFoundException: Path hdfs://b49691a74b48.jf.intel.com:8020/tpch_sf3000/lineitem/part-00281-3761d71a-87c6-4341-8f1c-db804f904130-c000.snappy.parquet does not exist.
