The next generation of Hadoop MapReduce Arun C. Murthy presented the plans for the next generation of Apache Hadoop MapReduce. The MapReduce framework has hit a scalability limit around 4,000 machines. We are developing the next generation of MapReduce that factors the framework into a generic resource scheduler and a per-job, user-defined component that manages the application execution. Since downtime is more expensive at scale high-availability is built-in from the beginning; as are security and multi-tenancy to support many users on the larger clusters. The new architecture will also increase innovation, agility and hardware utilization.
