{code}
0: jdbc:drill:schema=dfs> select * from t1 limit 1;
+------------+------------+------------+
| a1 | b1 | c1 |

Inner join between table and a view on the same table should work:
{code}
0: jdbc:drill:schema=dfs> select * from t1 inner join v1 on t1.a1 = v1.x;
Query failed: UnsupportedRelOperatorException: This query cannot be planned
possibly due to either a cartesian join or an inequality join
Error: exception while executing query: Failure while executing query.
(state=,code=0)
{code}
Self join works:
{code}
0: jdbc:drill:schema=dfs> select t1.a1, t1_alias.a1 from t1 inner join t1
t1_alias on t1.a1 = t1_alias.a1;
+------------+------------+
| a1 | a10 |
+------------+------------+
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 5 |
| 6 | 6 |
| 7 | 7 |
| 9 | 9 |
| 10 | 10 |
