----------------------------------
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.
