Jan van der Lugt commented on GIRAPH-259:
-----------------------------------------
That will be my bad. The problem is the master does not execute workercontext
functions, where the aggregators are usually being reset. Thus, the master
keeps on aggregating and never resets the values unless you explicitly specify
this. We could change the semantics to have all aggregators being cleared by
the default master.compute implementation at the beginning of each superstep,
so that the workercontext does not have to do this anymore.
Actually, I oppose the whole idea of the workercontext containing anything but
performance/memory optimizations (such as parsed strings or shared objects),
it's much easier to do all the aggregator processing in the master, since they
are being collected there anyways.
