Questions on behavior of Drill when querying on empty files/directories -
- 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.
