debug: confirmed root cause - Parquet tries to read 78 bytes past EOF
**KEY FINDING:** Parquet is trying to read 78 bytes starting at position 1275, but the file ends at 1275! This means: 1. The Parquet footer metadata contains INCORRECT offsets or sizes 2. It thinks there's a column chunk or row group at bytes [1275-1353) 3. But the actual file is only 1275 bytes During write, getPos() returned correct values (0, 190, 231, 262, etc., up to 1267). Final file size: 1275 bytes (1267 data + 8-byte footer). During read: - Successfully reads [383, 1267) → 884 bytes ✅ - Successfully reads [1267, 1275) → 8 bytes ✅ - Successfully reads [4, 1275) → 1271 bytes ✅ - FAILS trying to read [1275, 1353) → 78 bytes ❌ The '78 bytes' is ALWAYS constant across all test runs, indicating a systematic offset calculation error, not random corruption. Files modified: - SeaweedInputStream.java - Added EOF logging to early return path - ROOT_CAUSE_CONFIRMED.md - Analysis document - ParquetReproducerTest.java - Attempted standalone reproducer (incomplete) - pom.xml - Downgraded Parquet to 1.13.1 (didn't fix issue) Next: The issue is likely in how getPos() is called during column chunk writes. The footer records incorrect offsets, making it expect data beyond EOF. |
