[jira] [Created] (HAMA-771) Determining the count of active vertices.

Edward J. Yoon created HAMA-771:
-----------------------------------

             Summary: Determining the count of active vertices.
                 Key: HAMA-771
                 URL: https://issues.apache.org/jira/browse/HAMA-771
             Project: Hama
          Issue Type: Bug
    Affects Versions: 0.6.2
            Reporter: Edward J. Yoon
            Assignee: Edward J. Yoon
            Priority: Critical
             Fix For: 0.6.3


{code}
        // check for halt again after computation
        if (!vertex.isHalted()) {
          activeVertices++;
        }
        ....

        aggregationRunner.sendAggregatorValues(peer, activeVertices);  
{code}

To actually determine the count of active vertices of each superstep, it's necessary to count the number of activated vertices. So, it should not check  isHalted() twice.
