   May I know whats the new column you are adding just in writer2? In desc you are describing as `_hoodie_deleted_date`, but I don't see any such field in your target table schema. may be its a diff column is it. 
   Also, in general schema evolution works well if you add a new column to the end of the existing schema. if you add in the middle, I am not sure it might sit well. 
   Can you confirm this. please.
