Invalid compressed stream

Error message

Invalid compressed stream

What it means

Zlib decompression error in OrcZlibDecompressor: the inflater threw DataFormatException (or produced needsInput/finished inconsistencies), meaning the compressed bytes are not a valid deflate stream. Reported as 'Invalid compressed stream' — classic symptom of a corrupted or non-ORC file region.

Solutions

1. Check the file for corruption (checksums, re-copy from source)
2. Confirm the file is actually ORC/zlib-compressed as its postscript claims
3. Report file-level corruption to the storage owner
