dear,sir Thanks for watching this mail. I'm reading a doubt hive0.14. To modify and delete Operation, we added identifier.When I run the select ,hive0.14 reads every delta bucket.This means that it contains the original data and modifying data (or delete data),so I don't understand where the merged data . I hope to answer. Thank you once again
