[jira] [Created] (HAMA-999) Wrong size of MemoryQueue

JongYoon Lim created HAMA-999:
---------------------------------

             Summary: Wrong size of MemoryQueue
                 Key: HAMA-999
                 URL: https://issues.apache.org/jira/browse/HAMA-999
             Project: Hama
          Issue Type: Bug
          Components: bsp core
            Reporter: JongYoon Lim


I found that *SuperstepPiEstimator* example sometimes gives wrong result when call *peer.getCurrentMessage()*. And that was because of wrong *size()* of *MemoryQueue*. When I printed out sizes of queue from the example, sometimes it said, 
{noformat}
bundle size: 20, numOfMsg: 19, deque size: 0
{noformat}
I think *deque*, *bundles* and *numOfMsg* of *MemoryQueue* should be properly synchronized to get correct result.
