> Project: Hama
> Issue Type: Bug
> Components: graph
> Affects Versions: 0.6.4
> Reporter: Aguinaldo Pontes

>
> When implementing an algorithm on Apache Hama platform, we noticed that when
> the first vertex of the split received a message, all the others became
> activated (being previously halted), even if they didn't receive a message.
> We think that this happens in the line 254 in GraphJobRunner, in the
> doSuperstep method (
> https://github.com/apache/hama/blob/trunk/graph/src/main/java/org/apache/hama/graph/GraphJobRunner.java#L254).
> We think that in this line it misses the following verification:
> if(currentMessage!=null && ... )
> Could you confirm?
> Thanks.
