Suraj Menon commented on HAMA-535:
----------------------------------
Hi, Please check the link below for an outline of the solution that I want to
propose. The key difference here from the Hadoop MR is that since BSP Task can
communicate with each other, it can share the existent key distribution among
each other. We can have different strategies to choose which reducer to run on
what set of keys based on the key distribution that every peer gets. This is
handled in ReducerKeyDesignator.java.

> Suraj had the idea of implementing MapReduce on top of Apache Hama.
> This is generally possible because BSP is a generalization to MapReduce.
> We should just make up a simple API compatible version to Hadoop and put it
> into our example module.
