> The error looks like this now:
> {noformat}
> File 'hdfs://nn/books/books1G.csv' has an invalid version number: .99 This could be due to stale metadata. Try running "refresh s3db.books_s3".
> {noformat}
> It seems to be reasonably common that this happens because a non-parquet file is being queried in a parquet table.
> The error message should say something like "File 'hdfs://nn/books/books1G.csv' has an invalid Parquet version number: .99 and does not appear to be a valid Parquet file. This could be due to stale metadata. Try running "refresh s3db.books_s3"
