Hi experts When I am viewing the Hive plans, I notice that in Reduce Output Operators, there is a "property" named "sort order" and it's value is "+++" - may I know what's the meaning of the three plus signs? Sometime I also see one plus sign... Is there any document talking about this? Or where could I refer to the code?
