Description

I am getting an error with the below query:

Without metadata cache:

0: jdbc:drill:zk=local> select count(*) from orders where dir0 = 1995;
+---------+
| EXPR$0  |
+---------+
| 40      |
+---------+
1 row selected (0.205 seconds)

Create metadata cache and run query:

0: jdbc:drill:zk=local> refresh table metadata `orders`;
+-------+--------------------------------------------------+
|  ok   |                     summary                      |
+-------+--------------------------------------------------+
| true  | Successfully updated metadata for table orders.  |
+-------+--------------------------------------------------+
1 row selected (1.112 seconds)

0: jdbc:drill:zk=local> select count(*) from orders where dir0 = 1995;
