Oracle has introduced a new feature for Hadoop on the Oracle Big Data Appliance called Perfect Balance.

Perfect Balance distributes the reducer load in a MapReduce application so that each reduce task does approximately the same amount of work. While the default Hadoop method of distributing the reduce load is appropriate for many jobs, it does not distribute the load evenly for jobs with significant data skew.

We will cover an overview of Perfect Balances, What the API looks like and a demo on how to add it to MapReduce code.
