      Description

      Something I noticed while looking at kudu-table-sink.cc: we use the referenced_columns map to translate between the index into the output exprs 'j' and the index into columns in the Kudu table 'col', but we incorrectly use 'j' when calling into the Kudu table schema to check the nullability of columns.
