    Thanks for investigation. This is definitely very useful to the other Spark users. Maybe you can make a change the existing document http://spark.apache.org/docs/latest/sql-programming-guide.html and explain our implicit type casting? 
    
    So far, we do not have a perfect solution to avoid external behavior changes, if we use your changes.
