> Different query result depending on whether hive.cache.expr.evaluation is true or false.  When true, no query results are produced (this is wrong).
> The q file:
> {noformat}
> set hive.cache.expr.evaluation=true;
> CREATE TABLE cache_expr_repro (date_str STRING);
> LOAD DATA LOCAL INPATH '../../data/files/cache_expr_repro.txt' INTO TABLE cache_expr_repro;
> SELECT MONTH(date_str) AS `mon`, CAST((MONTH(date_str) - 1) / 3 + 1 AS int) AS `quarter`,   YEAR(date_str) AS `year` FROM cache_expr_repro WHERE ((CAST((MONTH(date_str) - 1) / 3 + 1 AS int) = 1) AND (YEAR(date_str) = 2015)) GROUP BY MONTH(date_str), CAST((MONTH(date_str) - 1) / 3 + 1 AS int),   YEAR(date_str) ;
