Edward J. Yoon commented on HAMA-444:
-------------------------------------

Simply, one way is that we can compare the size of znodes with the size of (jobConf.getNumBspTask()
- the number of completed tasks).

> Each BSP task can be finished differently with their each conditions. In this case, all
tasks should be finished at the last iteration or comparison logic of barrier should be fixed
to avoid hang problem.
