Date Thu, 25 Oct 2012 08:04:12 GMT
sandy ding created HAMA-659:
-------------------------------

             Summary: the globalError computation is wrong
                 Key: HAMA-659
                 URL: https://issues.apache.org/jira/browse/HAMA-659
             Project: Hama
          Issue Type: Bug
          Components: graph
    Affects Versions: 0.5.0
         Environment: VMWare Workstation 8
Debian 6

            Reporter: sandy ding
            Priority: Minor


In bsp() (GraphJobRunner.java), after each vertex is computed,the aggregate function is called
twice:
first aggregate(vertex, vertex.getValue()) is called,
then aggregate(vertex, lastValue, vertex.getValue()) is also called.
But actually only the latter one should be called.
