---------------------------------------

             Summary: Join between drill table and view created on the same table throws unsupported
exception
                 Key: DRILL-2345
                 URL: https://issues.apache.org/jira/browse/DRILL-2345
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 0.8.0
            Reporter: Victoria Markman
            Assignee: Jinfeng Ni

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;
+------------+------------+

+------------+------------+
| 1          | 1          |
