URL: https://github.com/apache/spark/pull/24253
 
 
   ## What changes were proposed in this pull request?
   After [23750](https://github.com/apache/spark/pull/23750), we may pushdown 
left anti joins below aggregate and window operators with a partial join 
condition. This is not correct and was pointed out by @hvanhovell and 
@cloud-fan 
[here](https://github.com/apache/spark/pull/23750#discussion_r270017097). This 
pr addresses their comments.
   ## How was this patch tested?
   Added two new tests to verify the behaviour.
