Cause: Before CSE optimization, there were two duplicate Alias expressions in the Project operator, both of which were 'event#33.event_info[type] AS type#0'. After the CSE Rule detects that it is a duplicate expression, it adds a pre-project operator for current project operator. The pre-project operation contains `event#33.event_info[type] AS type#0 AS event#33.event_info[type] AS type#0#83`, which is an Alias expression upon another Alias expression, and of course doesn't make sense. -- This is an automated message from the Apache Git Service.
