I got this error after renaming the file

+org.apache.spark.sql.catalyst.parser.ParseException
+
+no viable alternative at input 'year'(line 3, pos 59)
+
+== SQL ==
+SELECT empno, depname, salary, bonus, depadj, MIN(bonus) OVER (ORDER BY empno), MAX(depadj) OVER () FROM(
+SELECT *,
+  CASE WHEN enroll_date < '2008-01-01' THEN 2008 - extract(year FROM enroll_date) END * 500 AS bonus,
+-----------------------------------------------------------^^^
+  CASE WHEN
+    AVG(salary) OVER (PARTITION BY depname) < salary
+    THEN 200 END AS depadj FROM empsalary
+  )s

Also, it fails the ANSI table insertion policy:

I am thinking about reverting the PR #25816. After #26107 is merged, we can manage to add the window_part1.sql back correctly.

Since the Jenkins fails, the reverting is better. I reverted it. Thanks, @gengliangwang .
