Research direction

Start by reproducing the failure in ParquetWriterTest.kt at the test shown in the stack trace, then trace ParquetWriter.kt:75 through HadoopOutputFile.fromPath and Hadoop UserGroupInformation. Determine the project-side change needed for JDK25 compatibility, and verify that the parquet-writing test completes without the getSubject exception on JDK25.
