Hama 900 - Added a new strategy to schedule tasks based on round robin
scheme
In this pull request, I have implemented the TaskAllocationStrategy to
schedule tasks equally on cluster.
I ran multiple tests on my cluster including the PI example and my own
algorithm and everything was alright.
Following snapshot shows one such example. On my cluster with 9 machines
supporting 54 tasks, I ran a job with 18 tasks. In the screenshot you can see
the equal distribution in cluster with each machine only running 2 tasks.
