             Summary: Make buffer that rows are read into during execution configurable for testing purposes
                 Key: DRILL-2483
                 URL: https://issues.apache.org/jira/browse/DRILL-2483
             Project: Apache Drill
          Issue Type: Wish
            Reporter: Victoria Markman


We've found a bug recently where if table had multiple duplicate rows and duplicate rows span multiple buffers, merge join returned wrong result. Test case had a table with 10,000 rows.

The same problem could be reproduced on a much smaller data set if buffer size was configurable.
