kaka11chen opened a new pull request #10844:
URL: https://github.com/apache/druid/pull/10844


   Fixes #10842.
   
   ### Description
   
   The root cause is the sql described in #10842 will go to infinite loop by 
these rules.
   
   - `AggregateRemoveRule`
   - `AggregateProjectMergeRule` 
   - `SortRemoveRule` 
   - `SortProjectTransposeRule`
   
   Removing any of above rules which can avoid infinite loop. This patch remove 
`AggregateRemoveRule ` because `AggregateRemoveRule` for druid is not necessary.
