Advertising
- Empty directory case currently returns table not found. Consensus was that this is correct. Because without any files, Drill doesn't know which reader to use, and therefore, can't do any processing. Khurram will try this out and compare against the case of a directory with empty JSON/csv files, which should return no rows found. - Questions on recent UNION ALL handling of empty files. Khurram will discuss offline with Aman. - Directory with a metadata file but no data (due to user error in deleting data) -- Consensus was this should return an error since the metadata doesn't match with the non-existent data.
