             Summary: NPE when querying view with where clause and derived table
                 Key: DRILL-2051
                 URL: https://issues.apache.org/jira/browse/DRILL-2051
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 0.8.0
            Reporter: Victoria Markman

`customer.json`
{code}
{ "CustomerId": "100", "cityId": 10 }
{ "CustomerId": "101", "cityId": 10 }
{ "CustomerId": "102", "cityId": 10 }
{ "CustomerId": "103", "cityId": 20 }
{ "CustomerId": "104", "cityId": 30 }
{ "CustomerId": "105", "cityId": null }
{ "CustomerId": null,  "cityId": 50 }
{code}

{code}
0: jdbc:drill:schema=dfs> create view v3 as select * from ( select * from `customer.json` ) where customerid >= 100;
+------------+------------+
|     ok     |  summary   |
+------------+------------+
| true       | View 'v3' created successfully in 'dfs.identifiers' schema |
+------------+------------+
1 row selected (0.063 seconds)
0: jdbc:drill:schema=dfs> select * from v3;
Query failed: NullPointerException: 

Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Query by itself works fine:
{code}
0: jdbc:drill:schema=dfs> select * from ( select * from `customer.json` ) where CustomerId >= 100;
+------------+------------+
| CustomerId |   cityId   |
+------------+------------+
| 100        | 10         |
| 101        | 10         |
| 102        | 10         |
| 103        | 20         |
| 104        | 30         |
| 105        | null       |
+------------+------------+
6 rows selected (0.117 seconds)
{code}

If you remove where clause and leave just derived table in the view creation, you can query the view as well.
