If I'm not mistaken, aggregators are the recommended way to communicate
between master.compute() and (worker's) vertex.compute() in Giraph. I
personally don't know if it's the *on
Hi, Young
That is a choice.
But I just want transform A or B when each vertex computing , now I need
transform A and B. And in my program, the A and B are both somehow large.
Is there another way to share global variable between each vertex beside
getAggregatedValue() ?
thanks a lot !

Hi,
One way, though not a very clean way, would be to create an object that
encapsulates what you want to store in A and B. So, say you want A to be a
DoubleWritable and B to be a Writable object with two integers. Then you
could just create a Writable object having three fields: double, int, int.
hi all:
org.apache.giraph.aggregators has these tow methods:
void aggregate(A value)
A getAggregatedValue()
Now I want to use aggregate() in vertex_program to send value of type A for
global aggregating, however,
I want the output of custom aggregator is type B .
that is to say ,
