             Summary: CTAS with store.format = 'json' returns incorrect results
                 Key: DRILL-2906
                 URL: https://issues.apache.org/jira/browse/DRILL-2906
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - JSON, Storage - Writer
            Reporter: Mehant Baid
            Assignee: Steven Phillips
             Fix For: 1.0.0


Performing a CTAS with 'store.format' = 'json' and querying the table results in projecting an addition field '*' will null values. Below is a simple repro

0: jdbc:drill:zk=local> create table t as select timestamp '1980-10-01 00:00:00' from cp.`employee.json` limit 1;
+------------+---------------------------+
|  Fragment  | Number of records written |
+------------+---------------------------+
| 0_0        | 1                         |
+------------+---------------------------+
1 row selected (0.314 seconds)
0: jdbc:drill:zk=local> select * from t;
+------------+------------+
|   EXPR$0   |     *      |
+------------+------------+
| 1980-10-01 00:00:00.0 | null       |
+------------+------------+

Notice in the above result set we get an extra column '*' with null value.
