docs: comprehensive analysis of Parquet EOF root cause and fix strategies
Documented complete technical analysis including: ROOT CAUSE: - Parquet writes footer metadata AFTER last getPos() call - 8 bytes written without getPos() being called - Footer records stale offsets (1252 instead of 1260) - Results in metadata mismatch → EOF exception on read FIX OPTIONS (4 approaches analyzed): 1. Flush on getPos() - simple but slow 2. Track virtual position - RECOMMENDED 3. Defer footer metadata - complex 4. Force flush before close - workaround RECOMMENDED: Option 2 (Virtual Position) - Add virtualPosition field - getPos() returns virtualPosition (not position) - Aligns with Hadoop FSDataOutputStream semantics - No performance impact Ready to implement the fix. |
