> By HAMA-410 patch, BSPPeer object will be constructed at child process. Now we can just remove limitation on the number of tasks.
> Here's TODO list:
> 1. The number of tasks per groom should be configurable e.g., 'bsp.local.tasks.maximum'.
> 2. The 'totalTaskCapacity' should be calculated at BSPMaster.getClusterStatus().
> 3. When scheduling tasks, consider how to allocate them.
> 4. Each BSPPeer should know all created peers of Hama cluster by job. It can be listed based on actions of GroomServer.
> 5. In examples, 'cluster.getGroomServers()' can be changed to 'cluster.getMaxTasks()'.
