how can build key 2 components? reason have undirected graph. there edge between 2 nodes , b if , b associated through communication (the direction irrelevant). communication has numerical parameter. achieve have key combines , b set, communication b , b can considered equivalent , summed stats say: a b 5 b 10 the key should semantically "a or b together", set containing , b key should have value 5+10=15. the wordcount example has key specific words. in case, want have key set 2 components. during map , reduce phases, sum long b or b satisfies. thx! in addition (correct) answer david: if problem has graphs have @ http://incubator.apache.org/giraph/ also.

as known binding concept of declaring object of specific data type, , cant hold other type of object. while late binding concept of declaring object of generic type , can hold instance of other type. consider example: public abstract class animal { public virtual string name { { return "animal"; } } } public class dog : animal { public override string name { { return "dog"; } } } public class cat : animal { public override string name { { return "cat"; } } } public class test { static void main() { animal animal = new dog(); animal animaltwo = new cat(); console.writeline(animal.name); console.writeline(animaltwo.name); } } my question when compilor recognize function call of object, either @ compile time or run time? sorry if unclear. mean ask concept of virtual on riding , virtual methods involve late binding or not? .. if not how possible. runtime. a virtual function...
