Invalid file metadata

Error message

Invalid file metadata

What it means

ORC metadata-reading error: parsing the file metadata section's protobuf failed (InvalidProtocolBufferException), wrapped as 'Invalid file metadata'. The metadata region after the footer is malformed — corruption, truncation, or reading a non-ORC file with the DWRF reader.

Solutions

1. Verify the file was fully written and flushed
2. Check for block-level corruption on the storage system
3. Reproduce reading the file with another ORC tool
