Value is not null but nanos stream is missing

Error message

Value is not null but nanos stream is missing

What it means

TimestampBatchStreamReader.readBlock: a non-null value was indicated by the present stream but the nanoseconds secondary stream is absent from the ORC file, so the timestamp cannot be reconstructed — the file's stream layout is corrupt.

Solutions

1. Recreate the ORC file with a correct writer
2. Check for partial/corrupt files in storage
3. Skip the affected split via query fault tolerance
