Khurram Faraaz commented on DRILL-4553:
---------------------------------------

Is this over Parquet or JSON or CSV data ? Can you please share the query plan for the case where equi-join over two views  returns no results ?

> I have the following three views:
> create view view1 as select ..... from .... where username=user;
> create view view2 as select ..... from view1 as a, <file1> as b where a.col1 = b.col1;
> create view view3 as select ..... from view1 as a, <file2> as b where a.col1 = b.col1;
> A select * from each of these views works fine and returns the expected results.  A self join on view2 and view3 also works fine.  However when view2 and view3 are joined on common keys there are no rows returned.
