ueshin opened a new pull request #33547: URL: https://github.com/apache/spark/pull/33547
### What changes were proposed in this pull request? Fix `IndexOpsMixin.hasnans` to use `IndexOpsMixin.isnull().any()`. ### Why are the changes needed? `IndexOpsMixin.hasnans` has a potential issue to cause `a window function inside an aggregate function` error. Also it returns a wrong value when the `Series`/`Index` is empty. ```py >>> ps.Series([]).hasnans None ``` whereas: ```py >>> pd.Series([]).hasnans False ``` `IndexOpsMixin.any()` is safe for both cases. ### Does this PR introduce _any_ user-facing change? `IndexOpsMixin.hasnans` will return `False` when empty. ### How was this patch tested? Added some tests. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
