------------------------------------

             Summary: query returns incorrect data when columns selected in the reverse order
of their existence in the view
                 Key: DRILL-863
                 URL: https://issues.apache.org/jira/browse/DRILL-863
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Vivian Summers


I have a view beacon_aster, uid column appears before country and this works fine:
: jdbc:drill:schema=dfs> SELECT uid, country FROM beacon_aster limit 1;
+------------+------------+
|    uid     |  country   |
+------------+------------+
| 937021026  | US         |
+------------+------------+
1 row selected (6.52 seconds)

But if select country first, it returns other columns after uid:
0: jdbc:drill:schema=dfs> SELECT country, uid FROM beacon_aster limit 1;
+------------+------------+
|  country   |    uid     |
+------------+------------+
| US         | 937021026	2816d925-6902-2014-8017-113468677480	2012-09-25 00:00:27.132	20120906.02
60f2761d0e6192a88305054eb06877cb	1	-8	US	9 |

Some cases it throws error:
This works:
0: jdbc:drill:schema=dfs> SELECT recorded, country FROM beacon_aster limit 1;
+------------+------------+
|  recorded  |  country   |
+------------+------------+
| 2012-09-25T00:00:27.132-07:00 | US         |
+------------+------------+
1 row selected (8.279 seconds)

But this throws IllegalArgumentException, recorded columns appears before country column:

0: jdbc:drill:schema=dfs> SELECT country, recorded FROM beacon_aster limit 1;
