[GitHub] [drill] paul-rogers opened a new pull request #1867: DRILL-7358: Fix COUNT(*) for empty text files

paul-rogers opened a new pull request #1867: DRILL-7358: Fix COUNT(*) for empty text files
URL: https://github.com/apache/drill/pull/1867
 
 
   Fixes a subtle error when a text file has a header (and so has a
   schema), but is in a COUNT(*) query, so that no columns are
   projected. Ensures that, in this case, an empty schema is
   treated as a valid result set.
   
   Tests: updated CSV tests to include this case.
