             Summary: SELECT DISTINCT fails on char column
                 Key: DRILL-205
                 URL: https://issues.apache.org/jira/browse/DRILL-205
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Harri Kinnunen


This works:
SELECT distinct nation.name
FROM (
  SELECT _MAP['N_REGIONKEY'] as name 
  FROM "sample-data/nation.parquet"
) nation;

This fails (the difference is the 'N_NAME'):
SELECT distinct nation.name
FROM (
  SELECT _MAP['N_NAME'] as name 
  FROM "sample-data/nation.parquet"
) nation;
