The issue: grep pattern was wrong and looking in wrong place
- EOF exception is in the 'Caused by' section
- Filename is in the outer exception message
The fix:
- Search for 'Encountered error while reading file' line
- Extract filename: part-00000-xxx-c000.snappy.parquet
- Fixed regex pattern (was missing dash before c000)
Example from logs:
'Encountered error while reading file seaweedfs://...part-00000-c5a41896-5221-4d43-a098-d0839f5745f6-c000.snappy.parquet'
This will finally extract the right filename!
