CRITICAL: None of our higher-level logging is appearing!
- NO SeaweedFileSystemStore.createFile logs
- NO SeaweedHadoopOutputStream constructor logs
- NO FSDataOutputStream.getPos() override logs
But we DO see:
- WARN SeaweedOutputStream: PARQUET FILE WRITTEN (from close())
Adding WARN log to base SeaweedOutputStream constructor will tell us:
1. IF streams are being created through our code at all
2. If YES, we can trace the call stack
3. If NO, streams are being created through a completely different mechanism
(maybe Hadoop is caching/reusing FileSystem instances with old code)
