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

If you create a directory under j2 (2015), query works:

{code}
0: jdbc:drill:schema=dfs> select c_varchar from j2 where dir0='2015' limit 1;
+------------+
| c_varchar  |
+------------+
| 0000 000000 00000 |
+------------+
1 row selected (0.155 seconds)

0: jdbc:drill:schema=dfs> select c_varchar from j2 where dir0='2014' limit 1;
+------------+
| c_varchar  |
+------------+
+------------+
No rows selected (0.243 seconds)
{code}
