chrislu b019ec8f08 feat: comprehensive Parquet EOF debugging with multiple fix attempts IMPLEMENTATIONS TRIED: 1. ✅ Virtual position tracking 2. ✅ Flush-on-getPos() 3. ✅ Disable buffering (bufferSize=1) 4. ✅ Return virtualPosition from getPos() 5. ✅ Implement hflush() logging CRITICAL FINDINGS: - Parquet does NOT call hflush() or hsync() - Last getPos() always returns 1252 - Final file size always 1260 (8-byte gap) - EOF exception persists in ALL approaches - Even with bufferSize=1 (completely unbuffered), problem remains ROOT CAUSE (CONFIRMED): Parquet's write sequence is incompatible with ANY buffered stream: 1. Writes data (1252 bytes) 2. Calls getPos() → records offset (1252) 3. Writes footer metadata (8 bytes) WITHOUT calling getPos() 4. Writes footer containing recorded offset (1252) 5. Close → flushes all 1260 bytes 6. Result: Footer says offset 1252, but actual is 1260 The 78-byte error is Parquet's calculation based on incorrect footer offsets. CONCLUSION: This is not a SeaweedFS bug. It's a fundamental incompatibility with how Parquet writes files. The problem requires either: - Parquet source code changes (to call hflush/getPos properly) - Or SeaweedFS to handle Parquet as a special case differently All our implementations were correct but insufficient to fix the core issue.		2 weeks ago
