Well to be honest I would like to know the more internal stuff if it
wouldn't be
much of a burden to you. Thanks anyway!

In the end of every superstep (an some times before but let's keep
it simple) each aggregator is invoked and gets the value of each
vertex. Then all aggregators combine their status with 1 master
aggregator. On your next superstep you can read this aggregated
value from every vertex you have throughout the method
getLastAggregatedValue(0). (if you have more aggregators you will
need to change the number from 0 to an other).
If you want more internal stuff of how those actually work please tell me :)

Hey Anastasis,
Yeah I did check it but I can't figure out their work. So at each
superstep the aggregator takes the values of each node and calls
the aggregate function for each of them? And then at the next
superstep, we just call the getNextAggregatedValue with the index
of the aggregator we want, to get the result we return from getValue?

There is an example of Aggregators in PageRank example. Did you check it?

Hello there,
Sorry if my question is too naive but I cant find anything
myself..! I want to use a test aggregator in the Graph API but I
can't find how to call the aggregate function.. I can only see
getLastAggregatedValue and getNumLastAggregatedVertices. I am
also using hama-0.6.0.
Any help appreciated!
