CREATE TABLE x(a1 string);
INSERT INTO x VALUES ('aa'),('bb'),('cc'),('aa');
CREATE VIEW y AS SELECT row_number() OVER(ORDER BY a1) AS a1, a1 AS a2 FROM (SELECT a1 FROM x GROUP BY a1) AS t;

Gives:

2015-12-18 15:09:57 MSG trec2[17004]: could not find t.a1

The query works if I remove either the window function or the group by in the subselect.

Reproducible: Always
