             Summary: Keep new object creation to the minimum by reusing the Writable object
                 Key: HAMA-706
                 URL: https://issues.apache.org/jira/browse/HAMA-706
             Project: Hama
          Issue Type: Improvement
          Components: bsp core
            Reporter: Suraj Menon
             Fix For: 0.6.1


In all the examples and some core modules, we create new Writable objects, which is not recommended when we are handling huge data size with billions of records, causing a huge GC overhead. It is better that we reuse Writable object and populate the values instead. In places where the aforesaid principle is not followed, the suggested changes should be made. This would be useful once the spilling buffer is fully functional.
